I am working on a quilt top right now, a Pineapple Block Quilt, and what I am doing is making more blocks. It went from 20 blocks to 30 blocks to 42 blocks. Right now I am on block 35. They are 10" blocks. I haven't decided yet if I want it larger or not. Once I lay it out at 42 blocks I will know. I would consider adding more blocks or a border or even 2 borders to make it larger. A lot of your decision is going to depend on what your pattern is.
