I thought I would make up an example of one way you could put the Block-a-Long blocks together in a sampler format. This layout looks a lot more complicated than it really is. Remember each block is relatively easy.
Of course, there are a multitude of ways you could put together a sampler quilt. I was thinking that these blocks would lend themselves to a scrap quilt. As you get scraps large enough to make one of the blocks, make one, then eventually you would have enough for a quilt. It would be a nice memory of projects you did in a year or over a period of time.
