Thanks for all the info. I purchased the 6" one on-line from Walmart (local stores did not have it - I called around). Anyway, free shipping too! That saved me time and gas money. So, it will be here next week. I'm definitely excited about getting it....have lots of scraps to continue using and I was getting tired of making squares into patches and trying to come up with different ideas. This will enthuse me for years! Thanks for sharing the idea!
