All my f8s have been mailed. I used two different fabrics featuring Tinkerbell. Yes, I am old enough to remember when her name was spelled as one word, not Tinker Bell! All posts offices are different. Through six boomerang swaps, I have never had to fill out a form to send fabric to another country. And, I even asked about it the first time I mailed to Canada. The last swap, my husband was "helping" and mailed one to Canada with just $ .45 and it made it there without a problem. While we were on vacation in S.C. and in Florida, they tried to charge me for packages because the envelopes did not have paper in them, even though I had them slide them through the template slot. Silly people. I just brought them home and mailed them from Ohio.
