I have 35 squares, a toy and 3 skeins of wool to send. I packaged according to the instructions. I took the package to the post office. I put the package slip inside the package. I also put the address on the outside. I was told I need a customs slip. I have no idea where that is. I was also told my 4 lb package would cost $69. I feel like I've done all of this for nothing and that it would be better to keep the squares, etc. and donate money. Do these blankets really cost close to $200, given the cost of yarn and mailing? What am I missing? Thank you.
