I'm mailing from Canada, i just came from post office. As long as my pkg isn't over 2 kg it should cost me approximately $20.00. She never mentioned to me about any special box of pkging. The lady at post office gave me these bubble envelopes that she recieves the stamps in. She said these might work great for less weight (great recycling). So tonight i shall go through my stash and by monday morning it will be on its way to Spain.... i'm so excited. I've never done anything like this before, Izy hope you like what i send. Happy sewing everyone :D
