Following yesterday's CD case, I thought I'd post these pics of the mailers I sometimes use.
I haven't bothered with tute pics because they're so easy.
For the large one I used 2 pieces of 12x12 craft paper. I sliced about 8cm off the top of one piece. I measured out some bubble wrap to to size of the smaller piece, minus about 1.5cm margin all around. Cut 2 pieces, and stick on the wrong side of the papers. On the bigger piece, make sure you position the bubble wrap towards the bottom.
Then, I used sticky dots (or use strong craft glue or double sided tape) to stick down three sides - leave the top open for you to pop your bits in! Press the edges down hard, you might want to put it under a heavy book or something until it dries.
To seal, fold down the top tab of the bigger piece and I use double sided tape to secure.
For the smaller one, I folded a piece of 12x12 paper and then cut a rectangle out from one of the halves. To do this, slice down the crease about 4 or 5 cm, then across. Follow the instructions above (but this time obviously you're going to leave a side open).
These make really pretty mailers for when you just want to send a smallish thing, but remember that they are slightly heavier than a normal envelope so bear it in mind when posting!
