I asked about the tyrik?? envelopes and THEY are done by weight...where the cardboard ones are ONE flat rate. Go to another postoffice if you can...I find the smaller towns are more cooperative and willing to work with you..I bought my stamp and the envelope when I started this swap and they told me just to come back when I was ready to mail it and they would give me a tracking number...free!! I sure hope you don't drop out Abbys mom...its been a joy to work with you all these swaps!!
