The phone books here are small. Not much bigger then a paperback book. I buy the 10" square foundation papers from MSQC for string piecing. Also I have a box of deli papers used for sandwiches I use for foundation piecing. I got a 1000 sheets for about $5 at Sam's Club a few years ago. I never will use all those up. For paper piecing and printing the pattern, I bought a ream of lightweight vellum and it has lasted me for years and will last for years more.
