Named after the largest constellation, Hydra, this project is easy way to fancy up an unwanted string of Christmas lights. The light filtered through the knitted tube makes a gentle twinkling effect, and the long tube is an interesting object in itself when not plugged in. You can arrange your light in a clump, tie it in a knot, or suspend it as you would a regular string of lights.
Recommended yarns would be any basic wool yarn, not too fuzzy.
CAUTIONARY NOTE: please use a low flammability yarn for this project, and do not leave light unattended while plugged in! In general, wool should have a low flammability, while cotton and silk are higher-flammability. Acrylic isn’t as likely to ignite as cotton, although if it does ignite it may melt and make a mess. This site has some general information about fiber flammability: http://www.ci.knoxville.tn.us/kfd/what2do/fabrics.asp Flammability concerns are more important if you’re planning on using this on a flammable Christmas tree or on arranging the lamp into a pile, which will cause it to retain more heat than if hung straight.
