I recently ventured into the arena of tee shirt yarns. The two I have tried are Tee Cakes by Hikoo Skacell and Be Sweet T shirt yarn. I had to buy them online as they are not often carried in the NM yarn stores
Be Sweet T shirt yarn
My first project was a purse pattern in the spring issue of Vogue Knitting.
This was a really fun knitting project... I can't wait to try another.
