ILoveToQuilt

Hi All. Not sure I understand the swap completely. (By the way, All the blocks are awesome).

- If I only send a set of 4 blocks, does that mean I only get 4 blocks in return?
- Do all of my blocks need to be the same?
- Not understanding return postage requirements. (It is way-y-y-y past my bedtime of O'dark o'clock).

I am thinking I'd love to join in, but just not 100% sure of the requirements. I've never swapped before.

Thanks for your patience.
