Will try to get her to take a pic and send it to me--she does not have the Net at home right now...
She uses 1/4" or wider. prefers 1/2" or so.
I roll them up in a ball using the "cut a slit and pull through" method so there are no knots in the ball. I have sent her eight balls so far, and have four here...about 1/4 the size of a basketball. she is making a BIG rug for her dining room.
a neighbor of mine just brought sheets to me so Jenn(DD) can make her a heart shaped crocheted rug for her kitchen and two for her bathrooms---
