This is the solid color version of this stretchy Cascade yarn which is fun to knit, and works great with swimsuits or other garments where stretch is required. Fixation yarn is made from Cotton and Elastic so it is good for those who have allergies to wool or find wool to be scratchy. Fixation yarn is also popular for new born baby hats, or for chemo hats for friends with cancer or donating to cancer hospice organizations around the country.
