Page 3 of this thread has a picture of a quilt made from different size blocks.

Everyone has been so helpful and answered all my questions. DonnaJean...I love the Garden Quilt! That was the idea I had in mind. I also figured there was a way to draft quilt blocks, but felt a little intimidated. Time to Learn! I also love the idea of combining small sizes to make 12 inches. I am feeling better about starting my project! Just don't hold your breath for a picture too soon....This project is in my head....There are several more on the sewing table....Thanks again....

I posted the "picture" of the In My Garden quilt that came with the BOM pattern directions. When I made it, I did not want a quilt that big, so I just used some of the blocks & arranged them to my suiting. I have not taken a picture of "my" version of that quilt, so I guess I should.

I made a quilt using left over blocks from other projects. They ranged in size from 4" to 15" and inbetween. I used strips added to blocks that needed them to get a row the same size. Turned out well! Wish I had a picture to send so you could see how it was done. I am calling the quilt, "Orphans Home."

here is my favorite, as the different blocks all mean something to me; left over from one of my sisters, left over from my son and his wife when they got married 10 years ago.

Love Blluphrogs math. So simple but I nevert hought of it. Thanks

I am loving the orphan block idea! It seems like just what I had in mind. It is a beautiful quilt and I am sure it means a lot to you.
Donna Jean....I just assumed it was your quilt...I am sure yours is more beautiful!!!
Thanks again for all the great ideas!

These will all work, except the 8" block. To make that a 12 inch block, you need only one 8" block and five 4" blocks. Your graph paper will show you that. Two 8" blocks make 16 inches, and that's too big.

maviskw, I think Bluphrog was imagining the 8" block next to a 4" block, then below that the 4" block first, next to the other 8" block. In my head that looks to me like it would require sewing partial seams to put that particular four patch together.

Here is a quilt I made using different size blocks. But I stuck with only 3 sizes. 12", 6" and 6" x 12" finished. As long as all your blocks are even divisible you can make them as many different sizes as you want but it is an easier project to put together if you narrow it down to 3 or 4 sizes:
