People who knit can easily find summer projects to create that do not involve heavy yarn, wool or large items. Save the Afghans for the fall. Try something light, small and with summer fibers.
Socks are an option any time of year. You can knit them one at a time or two at a time on a magic loop. For the warm weather, use cotton, bamboo or linen based sock yarn instead of wool fibers. Simple or complicated, there are tons of free sock patterns available online. If you are up for a real challenge, try this Reptilian Lace sock with beads.
Another option is a summer wrap, like a shawl or shrug. Again, use lightweight summer fibers and you will not be sweating under a big pile of wool while you work. Lacy shawls, vests and shrugs look amazing and complex. You will be sure to get compliments while knitting and wearing your completed work! Here is a free pattern for Summer Whisper Wrap.
Make your favorite lightweight or lacy scarf pattern into a warm weather wrap by making it double the width. Just wrap it around your shoulders and voila – it is a shawl. Try this Laughingbird Scarf, double the number of stitches in the pattern and it will become a shawl.
Metallics mixed with bold colors are really in this summer. Knit with that, and become the envy of your peers with a gorgeous summer wrap. People will regard you as a fashion trendsetter. Check out this Touch of Shine Shrug.
There are those people who like to gear up for winter by knitting up a storm in the warmer seasons. If you have a spouse who likes to keep the AC really cold, maybe this will work!?
Summer knitting can be just as fulfilling as knitting by a roaring fireplace in the dead of winter. Just be sure to find the appropriate fiber and weight for the warmer weather. Get creative and adjust a winter pattern to suit the spring and summer.
