I know we were chatting in the June sign up thread about this but I thought it deserved it's own thread that we might can refer back to. Since I lived in the UK and ended up shipping 9 boxes of personal/home goods back and forth, I feel comfortable shipping to the UK. But recently one of my pocket page envelopes was returned. It was in limbo in the postal system a long while too. I feel bad b/c I try to get my international ones out earlier in the month. I've been mailing mine in a standard size envelope folded down. The reason being is that my post office said that you can eliminate the need for a customs form that way. While you can't track it, and it can take longer, it is less likely to be tagged for customs fees, and if the proper size or smaller, it needs no form and costs around 2-5 dollars generally for the postage. Randomly one came back and they can only speculate as to why. It was a tad thicker than my usual and the UK requested a customs form. It added 10 dollars to the cost (which isn't a big deal or a problem for me) and a customs form. I have an excellent USPS office with two VERY NICE employees who know their stuff. I've been so impressed. She told me she thought it was SO ODD they sent this one back. So I thought maybe the others who chimed in could mention their tips on how to send pocket pages internationally. My tips would be to keep your papers on the thinner side and fold them into a standard envelope so they pass as a letter. Check what the regulations are for the country you are sending to... For example, I love to send a tea package in mine, but it may not be allowed. Visit your local post office or mailing center in person to discuss the best ways to mail. You may get different suggestions from different people. If you can, find a place to mail that has the same person on a regular basis. It helps to "make friends" and let them know or even show them the art you are sending.
