mail them in an envelope! lol. I find this the best way. I rarely use priority its too expensive and the way the post office returns your money for lost things is amazingly slow and usually they give you less than you paid so I figure mail them and just hope. It usually runs around 3.00 or less in the US.
We do have one international player this month so if you feel you can mail internationally let me know! I will pair you up as partners and do this early so fabric is sent with time for shipping to arrive when the rest are coming in!
