crazy mom quilts: How to make a Pineapple Block (without paper piecing!) by amandajean I varied the strips in the block from 1.25" wide to 1.75" wide. These blocks can be made any size...I started with 14" blocks ..but bumped up the size to 16" after I made a few. This seems to be an ideal size for this strip width and 20 blocks will make a perfectly sized lap quilt. Keep an eye on your values (lights and darks), so the pattern emerges and is consistent throughout.
