Attn: Swappers..
I have found a great use for all those return mail labels I rec'd when I make donations (especially to animal protection). I'm getting soooo many. Anyway... I put them on back of blocks I swap.
Just a suggestion as what to do with 'em. It's nice to find a block you've swapped years ago & there is a label as to who it's from....
Just sayin'.....
