Definitely send with receipt confirmation. I think we agreed to include a 12 1/2" extra block, using scraps from the blocks we used for our added row. Our name and date etc. should be somewhere on that one. Or maybe just our name and date. The 5th block we need to make a complete row across the back can be the "signature" block we all add our names to. I plan on sending that one along with my row. Think of it as a big quilt label. It doesn't necessarily need to be 12 1/2" square, but I want to fit it in between the 4 extra blocks. Clear as mud? I'll try to make an example of what I mean and post it later on. Let me know if y'all t hink this is too much work and I'm overdoing it. I just thought it would be fun to have unique backs.
Oh yeah, don't forget the journal.
