Here's a link to the Amazon site for the book Kathy mentioned. If you scroll down through the page there are several different books listed with the same theme:

Hi Patsy, Sharyn Craig has a great book about basically doing that. I think it's called Setting Solutions.
Putting unifying frames around blocks can really make the blocks look like they belong together, as well as reconcile different sizes.
Pieced sashing is another idea. Kathy

Wow that is awesome! That really helps me alot...thank you so much....now to get the blocks out and on my design board.

I'm working on one right now! The blocks are all wonderful friendship gifts from special friends and I'm using extra green fabrics that were sent with the blocks to set them all together. It's a real puzzle, but I'm enjoying the challenge. This is what I have so far:

Have any of you ever took a whole bunch of different blocks you've made of all different colors, shapes and sizes and made a sampler quilt out of them? I'm thinking of making one out of a bunch of blocks I have.....should they all be tied together with one particular fabric? If anyone has done this and can share a photo, it might help me...TIA
