Another idea for a sampler quilt would be to make quilt blocks based on a theme. For example, star blocks. Can you believe Nancy Cabot had already published 35 of them in her Chicago Tribune column in the first nine months of publishing her patterns?
I have compiled a list of her star blocks with links to the posts that are written about each block. Most of the posts also link to a pattern to make that particular quilt block. But, some posts may tell you how to make the block right in the post or may link to a tutorial.
I will add to this list as new star blocks are added.
