Can you see how the yarn rests on my tension hand while I crochet? This is the result of the crochet marathon I have been on for the past month. This is the point where I put a band-aid on it. Also, Clover makes a little "yarn guide" thingy that you can put on your finger to hold the yarn. I have a few of those too. In the past, when I have kept crocheting without a band-aid, I have literally cut my finger on the yarn. I don't know if this would happen with all types of fibers, but when the yarn actually cut my finger, it was acrylic yarn. Now, I don't let it get to that point :) And while it is not usually this bad, as in the photo, pretty much, no matter how much I crochet, there is always a shadow of yarn embedded in my finger. Aren't you glad I shared that little tidbit?
