I have been wanting to make some quilts using small 1/2 sq. triangles but the idea of making all those little blocks seemed overwhelming. No longer. These papers actually make the process fun and easy to accomplish. Those little blocks adds so much interest to a quilt and takes your quilts from "that's nice" to "WOW". These papers make it possible to make perfect little blocks. You can use them with precuts or cut your own 5" squares.
