Whether you have been crocheting for decades or you are just starting to move beyond simple squares and scarves, this pattern has a way of calling to you.

By the time you finish reading, you should feel ready and genuinely excited to cast on.

What Is DROPS 99-28 Summer Sweetheart?

DROPS 99-28 is a free crochet pattern published by DROPS Design, the Norwegian yarn and pattern company that has been offering free, high-quality patterns to the crafting community for many years. The pattern is part of their DROPS 99 collection, and it produces a delicate, feminine pullover sweater worked in a combination of solid and lace-style crochet stitches.

The garment is designed to be lightweight and airy, making it ideal for warm weather. It features a flattering silhouette with a slightly relaxed fit, making it comfortable to wear over a swimsuit at the beach, layered over a tank top during a summer evening, or paired with linen trousers for a casual but polished daytime look. The name Summer Sweetheart suits it perfectly — it is the kind of top you reach for again and again when the temperature rises and you want to feel effortlessly put-together.

What makes this pattern stand out in the enormous sea of free crochet sweater patterns is its combination of accessibility and elegance. The stitch pattern is not overly complicated, which means even relatively new crocheters can tackle it with patience and care. But the result looks genuinely beautiful — intricate enough to earn compliments, wearable enough to reach for constantly.

The Yarn: DROPS Cotton Viscose

The original pattern calls for DROPS Cotton Viscose, which is a yarn that deserves a little attention on its own. Cotton Viscose is a blend of 54% cotton and 46% viscose, and that combination does a lot of clever work in a summer garment.

The cotton component gives the yarn structure and breathability. Cotton does not trap heat the way wool does, which makes it comfortable against the skin during warm weather. The viscose component — sometimes called rayon — adds a beautiful drape and a subtle sheen. When you finish a garment in Cotton Viscose, it falls softly and moves with you rather than holding a stiff shape. That fluid quality is part of what gives the Summer Sweetheart its graceful look when worn.

The yarn is a DK weight, which sits comfortably between lightweight and medium weight. It works up quickly enough that you will see steady progress on your project, but it is fine enough to produce the delicate texture the pattern calls for.

For color choice, the pattern has been shown in light, soft shades that emphasize the summery feel — cream, pale pink, soft sage, and light blue are all popular choices among crafters who have made this pattern. That said, bolder colors work beautifully too. A deep coral, a rich teal, or even a classic navy can give the finished sweater a completely different personality while the elegant stitch work remains the star.

If you cannot access DROPS Cotton Viscose in your local yarn store or prefer to substitute, look for a DK weight cotton-blend yarn with good drape. Yarns with a viscose, bamboo, or Tencel component will mimic the feel of the original yarn most closely. Avoid yarns that are too stiff or too thick, as these will change the drape of the finished garment significantly.

Hook Size and Gauge

The pattern recommends a 3.5mm crochet hook, which is relatively fine and creates a somewhat dense but still drapey fabric when paired with Cotton Viscose. As always with garment crochet, gauge matters enormously here.

The gauge for DROPS 99-28 is typically listed as a specific number of stitches and rows per ten centimeters in the main stitch pattern. Before you begin the sweater itself, take the time to make a gauge swatch. This step feels like an interruption to the fun of starting your project, but skipping it is one of the most common reasons crochet sweaters end up too large, too small, or oddly shaped.

To swatch properly, crochet a square of at least fifteen centimeters using your hook and yarn, work in the main stitch pattern, block the swatch gently the same way you plan to block the finished sweater, and then measure carefully. If your swatch is larger than specified, try going down half a hook size. If it is smaller, go up half a size.

Tension varies from person to person, and even the same crocheter may work more tightly in a new stitch than in a familiar one. Give yourself the grace of that swatch time.

Pattern Construction and Structure

The Summer Sweetheart is worked in separate pieces that are then seamed together — a front, a back, and two sleeves. This traditional construction method gives the garment a clean finish and makes it easier to match your gauge across different sessions of working.

The body of the sweater uses a combination of basic crochet stitches arranged into a lace-influenced pattern. DROPS patterns are known for incorporating mesh-style or shell-stitch elements even in garments that are not exclusively lace, and the Summer Sweetheart is a good example of this approach. The openwork sections create that breezy, summery quality without making the garment so delicate that it feels fragile or impractical.

The neckline is graceful and feminine — not so low as to feel immodest, but scooped enough to frame the collarbone nicely. The sleeves are designed to be short or three-quarter length depending on the size and the crocheter’s preference, which adds to the warm-weather appeal.

One of the things crocheters consistently appreciate about this pattern is that the stitch repeat, once established, develops a pleasant rhythm. The first few rows require close attention to the instructions as you get familiar with the sequence, but before long you will find yourself working through the motif with ease, and that is one of the most satisfying feelings in crochet — when a complex-looking pattern becomes fluid and intuitive in your hands.

Sizing and Fit

DROPS Design offers their patterns in a generous range of sizes, and DROPS 99-28 is no exception. The pattern typically covers sizes from small through extra-large or beyond, with measurements given in the pattern instructions so you can choose the size that will best fit your body.

When choosing your size, it helps to take your actual measurements and compare them to the finished garment measurements listed in the pattern rather than relying purely on the named size labels. The ease — the difference between your body measurement and the finished garment measurement — built into this design is relatively relaxed, which suits the casual, summery spirit of the piece.

A few tips for getting the fit right. If you are between sizes, the fabric’s natural drape and the openwork structure mean you can often go down a size for a closer fit or up a size for a more relaxed look without compromising the garment too much. If you have a longer torso than average, consider adding a few extra rows to the body before beginning the armhole shaping. If you prefer a slightly longer sleeve, this is also easy to adjust by working additional rows before the sleeve cap section.

Garment crochet rewards a little forethought. Laying out your pattern, reading through it completely before you begin, and noting any adjustments you want to make before you start your first chain will save you a lot of time and frustration later.

How to Read a DROPS Pattern

If you are new to DROPS Design patterns, a few things are worth knowing before you dive in. DROPS patterns are written in a concise, somewhat abbreviated style that assumes a basic familiarity with crochet terminology. Abbreviations are generally standard international crochet abbreviations, and the pattern will include a key.

DROPS patterns are also translated from Norwegian into many languages, and the English versions are generally clear and well-written. If you encounter a phrase or instruction that seems ambiguous, the DROPS website is an excellent resource — they have a video library covering many of their techniques and stitch patterns, and their community forum is active and helpful.

One aspect of DROPS patterns that sometimes surprises newer crafters is the level of trust they place in the reader. The instructions are accurate but not exhaustively hand-holding. You are expected to know how to make a foundation chain, work basic stitches, decrease, and so on. If any of these skills are new to you, spending some time on practice swatches before beginning the sweater will make the experience much more enjoyable.

Blocking Your Finished Sweater

Blocking is one of those finishing steps that genuinely transforms a crochet garment, and with a cotton-viscose yarn like the one used in this pattern, it is particularly impactful.

To block Summer Sweetheart, wet the finished pieces or the assembled sweater thoroughly in cool water, gently squeeze out the excess water without wringing, and then lay the piece flat on a blocking mat or clean towels. Shape it to the correct measurements, pinning if needed to hold the lace sections open, and allow it to dry completely before moving it.

What you will notice after blocking is that the stitches even out, the lace sections open up beautifully, the drape improves, and the overall proportions of the sweater become much cleaner. Blocking is not optional with this kind of pattern — it is genuinely part of the making process.

Styling Summer Sweetheart

Once you have finished your sweater and watched it transform through blocking, the fun of wearing it begins. The Summer Sweetheart is one of those pieces that works across a range of casual and semi-casual settings.

For a beach or resort look, wear it over a bikini top or bandeau, paired with linen shorts or a flowing skirt. The openwork texture lets sunlight through beautifully and creates a lovely layered effect. For a daytime brunch or casual outing, pair it with high-waisted jeans and sandals. For an evening garden party, wear it with a midi skirt in a complementary color and some delicate jewelry.

Because the sweater itself has considerable visual interest from the stitch pattern, it tends to work best with simple, unfussy pieces underneath and around it. Let the crochet work be the star.
