many of us use sandwich baggies to put our individual sets in. some of us use the clear plastic jewelry bags from craft stores to put our sets in. either way is fine. i have found that around $3.30-$3.60 is a good estimate for the sase return postage. i have taken my sase with baggies to the post office before to have them weighed and that is about near what the postage is. i am trying to include just a bit more over what the usps estimate is to account for the different size baggies used and the weight of the various fabrics. i hope this answers your questions.
cmon and join us. you know you want to.
