I have a new pattern for sale. It's called "rustic heart plant doily" - it measures 12" and I crocheted it with cotton twine. Over on the right sidebar is a small picture of it - click on that and it will take you to my 'patterns for sale' page where you can purchase the pattern.
I had bought the cotton twine from the Dollar Tree to fix up a pair of cardboard tube nunchuks (I don't know how to spell that correctly) for my grandson James and later on that evening I picked up the roll and started crocheting. This cotton twine is surprisingly soft - and you can't beat it for $1.00. I used a little less than 1 roll.
