For most people, the image of yarn work conjures up cold winter nights snuggled up in a thick sweater or blanket but knitting isn't just for cold weather wear. There are many different threads and yarns that could work for crocheting warm-weather wear. Typically, for summer wear, you might want to go with a crochet thread or fine yarn. Check out this page for a few suggestions for where to buy crochet thread.
For summer threads you really want to go for lighter fibers that will allow your garment to breath more. Thick wool may be great for a cozy winter night but it'll feel stifling in most summer weather. Here are my top choices for summer yarns.
Cotton is a summertime favorite for many. An organic cotton yarn is preferred by many for a variety of reasons. Many believe organic cotton is better for the environment because it doesn't use harsh pesticides. Some also believe that not using harsh chemicals makes the cotton better for your health. Knitpicks Simply Cotton Worsteds, lighter sport weight version of the yarn is equally lovely and possibly a better choice for summertime wear, depending on what you want to make and where you live. Cotton also breathes more than synthetic materials.
If excessive sweating is a problem for you then cotton is a great choice of material. It's absorbent and dries quickly, so unlike other materials, you won't just be trapping sweat against your body in the summer.
While sweat is great for cooling your body when combined with the wrong material it can actually cause your skin to break out. If this is an issue for you cotton may help.
Silk is also nice for both summer and winter wear. It's magically cool in the summertime and warm in the winter, so it's a great choice if you can afford it.
Unfortunately, it tends to be really expensive. Also, you have to be a little bit careful in choosing what you make with it because silk can "grow" over time. The yarn will stretch over time which could ruin the look of some garments. So it's best not to make, for example, tight fitted tops using silk because they might not retain the fitted look for long. Drapey flowing garments are a better choice.
Silk blends can be lovely for summertime wear and are sometimes less expensive too.
Spring and Summer Patterns
Finding the proper yarn for warm weather is just as important as finding patterns for spring and summer wear. Luckily many such patterns exist for free online. Knitting doesn't have to be limited to just chunky sweaters and mittens. You can knit or crochet anything from halter tops to skirts and light beanies. The only limitation is the patterns you're willing to attempt.
