Keep watching this and have soooo much fall fabric, just 1 question, when we send our blocks in, do we get 1 of our own back?? Also, if we send all 12 1/2" blocks, if someone sends all 6 1/2" is it an even trade 1 for 1 or would we receive 2 for 1? Don't know so have to ask, always been in them where they are the same size.
