I'd like to know also. Thanks for posting this question

I am not sure the difference in stack & whacks and OBW's but from what I have done and seen on here the stack & whacks usually use a background fabric for piecing and the OBW's seem to be just the blocks all sewn together without any other fabric...someone please correct me if I am wrong.
I personally prefer the stack & whack quilts.

I made one and loved how the blocks were so differant. Yours is going to be great. Good job.

I like it!

That looks really nice:)

Love it! Great job!

I like that block - bet the rest will be just as interesting!

Thanks its pretty fabric so hopefully it will look nice..whack and stack are different because they use 2 fabrics...the one block wonders just use one piece of fabric...both are cool, I think whack and stacks are faster because they are larger blocks..When I finish I will post the quilt...Thanks

Keep going, it will be such a neat quilt!! :thumbup:

Very pretty. I love how it's turning out. That is going to be a beautiful quilt. Thanks for sharing.
