Hi: I'm getting close to putting my blocks in the mail but wanted to ask if people are buying a ppd mailer to enclose with the blocks they mail in so Dagney can mail the swap blocks back or do we just enclose the amount of the postage? I will do either one but want to know so I can get it ready before I go in for my hip replacement surgery. My DH will be my "chief step and fetcher" for awhile and I'd like to have as much done as I can before I have the surgery to help ease DH's workload. Thanks for sharing your suggestions. Feathers
