Caron Cotton Cakes vs Simply Soft: Which Yarn for Summer?
Summer knitting and crochet call for yarns that breathe, drape well, and hold up to frequent washing. Choosing between cotton vs acrylic yarn can make or break your warm-weather wardrobe pieces.
We make both Caron Cotton Cakes—a 100% cotton option—and Simply Soft, our flagship acrylic. Each fiber behaves differently in heat, handles moisture its own way, and shapes finished fabric with distinct characteristics. This guide walks through fiber performance, project suitability, and care to help you pick the right yarn for your next summer make.
Breathability and Heat Retention
Cotton absorbs moisture and releases it through evaporation, pulling heat away from skin. A cotton tank top or tee worn in 85°F weather stays cooler against the body than an acrylic equivalent because the fiber doesn’t trap warmth the way synthetic materials do.
Acrylic yarn, including our Simply Soft line, is hydrophobic—it repels water rather than absorbing it. That trait keeps garments lighter when damp but also means the fabric holds body heat close. For garments worn directly on skin in summer, cotton typically feels more comfortable. For layering pieces or accessories like market bags, acrylic’s quick-dry property becomes an advantage.
Drape and Stitch Definition
Cotton’s weight gives it natural drape. A shawl or cardigan made in Cotton Cakes hangs with defined edges and crisp stitch work—cables and lace patterns stay sharp through wear and washing.
Simply Soft is lighter per yard and has more spring. That bounce helps maintain shape in structured garments like fitted tees or shaped bags, but it can soften stitch definition in textured patterns. Readers working with our speckled colorways sometimes encounter this trade-off; we address stitch clarity challenges in speckle yarn in a separate troubleshooting guide.
Weight Per Yardage
Cotton Cakes deliver approximately 250 yards at 200 grams. Simply Soft offers 315 yards per 170-gram skein. The density difference means cotton projects require more skeins for the same garment size, which affects both material cost and finished weight.
Washing and Long-Term Durability
Cotton tolerates hot water, bleach when needed, and tumble drying on medium heat. A cotton dishcloth or baby blanket can go through dozens of wash cycles without pilling or losing shape—the fiber actually softens with repeated laundering.
Acrylic maintains color vibrancy longer but needs gentler care. Simply Soft should be washed in cool or warm water and laid flat or tumble-dried on low to prevent stretching. The fiber doesn’t break down with washing the way cotton can after years of heavy use, but it will pill if agitated too aggressively. According to the American Chemical Society’s overview of synthetic fibers, acrylic’s molecular structure gives it excellent resistance to sunlight and chemical degradation, making it suitable for outdoor items like bunting or picnic blankets that won’t see high-temperature washes.
Shrinkage and Blocking
Cotton shrinks 3-5% in the first hot wash if not pre-washed. Blocking cotton lace or garment pieces before seaming is essential—pins hold the fabric in place while it dries, and the shape stays locked. Acrylic doesn’t shrink or block in the traditional sense, though steam blocking can relax stitches temporarily.
Color Range and Self-Striping Options
Simply Soft comes in over 40 solid colors and variegated options. Our Cotton Cakes line offers self-striping gradients—automatic color changes built into the cake’s wind pattern—which eliminate the need to carry multiple strands or weave in ends for striped projects.
Cotton absorbs dye deeply, producing saturated, matte colors. Acrylic takes dye differently, yielding slightly shinier finishes and softer pastels. If you’re deciding between self-striping options across fiber types, we compare Cakes versus Big Cakes construction in another guide—both use the same gradient wind, but Big Cakes deliver more yardage per unit.
Matching Fiber to Project Goals
Cotton vs acrylic yarn isn’t a universal preference—it’s a decision driven by the specific demands of each project. Cotton Cakes deliver breathability, drape, and washability for garments and home goods that see heavy use in warm weather. Simply Soft offers lightweight comfort, vibrant color retention, and easy care for everyday wearables and quick-dry accessories.
Consider climate, washing frequency, and the fabric hand you want in the finished piece. Both fibers perform well in their intended roles; choosing between them comes down to which set of properties aligns with how you’ll actually use what you make.
Common Questions About Cotton and Acrylic Yarn for Summer Projects
Cotton has minimal elasticity and can grow slightly with wear, especially in garments like sleeves or hem edges that bear weight. Ribbing in cotton requires tighter tension than acrylic to maintain shape. Blocking finished pieces before wearing helps pre-set the fabric and reduces stretch during use.
Gauge often differs between fibers even at the same weight class. Cotton is denser and less stretchy, so a pattern written for acrylic may produce a smaller, stiffer fabric in cotton at the same hook or needle size. Always swatch both yarns and adjust tool size to match the pattern’s stated gauge before committing to a full project.
Both are safe for baby projects. Cotton is hypoallergenic, breathable, and withstands the frequent hot washes baby items need. Acrylic is softer against newborn skin and lighter in weight, making it easier for infants to move under blankets. Choose based on climate and washing routine—cotton for hot climates and high-temperature laundry, acrylic for everyday softness and quick care.
Cotton absorbs water and takes hours to dry, making it poor for items left outside or used near pools. Acrylic sheds water, dries quickly, and resists mildew, which suits outdoor cushions, picnic blankets, or patio decor. Cotton excels in indoor settings where absorbency is an asset, like kitchen towels or bath mats.
Cotton fibers are plant-based cellulose, naturally firmer than acrylic’s petroleum-derived polymer chains. The stiffness softens after the first few washes as the fibers relax. Acrylic feels plush immediately because it’s engineered to mimic wool’s softness without the same break-in period.
Mixing fibers in a single piece creates care conflicts—cotton needs hotter washes and can shrink, while acrylic requires cooler water and no heat drying. If you colorblock or stripe different yarns, treat the finished item according to the most delicate fiber’s needs, which usually means following acrylic care instructions and accepting that the cotton portions won’t get the deep clean they could handle alone.
