hi guys! missy just introduced me to this board and it's great!
i haven't been able to make any of these in a while (knitting takes up most of my crafty time) but they are pretty easy and make great gift boxes for small items
small paper mache boxes (i got mine at michael's...they are usually about a dollar a piece i think but they go on sale sometimes, and come in lots of shapes/sizes!)
old postage stamps (i got mine from friends in other countries, off ebay, or from stamp collecting shops that have big bins of old stamps you can buy by weight or real cheap by the piece)
felt (i used felt squares from the crafts department at wal*mart)
sort through your stamps and decide which ones you like best and want to show the most, and which ones aren't as great that you can use as gap fillers
paint the part of the box you want to start covering with mod podge and lay down your first stamp. if you don't want it to be completely covered, leave a corner up so you can slide another stamp under there. it just depends on how anal you are about the layout of the stamps.
keep pasting more stamps on the box until it's covered. i don't fold over the stamps that extend past the edge, i wait til i'm done and it's dry and then slice the excess off with a razor blade. if you wanted to go all out you could cover the inside and the outside of the box, but when it gets to the corners it can be tricky--this is true for the outside of the box too, and sometimes you have to do some creative cutting and folding to keep the stamps from getting bunched up.
put a couple more coats of mod podge over the whole thing until it looks good for you. i guess you could use fine sandpaper between coats but i have not done this. you can see brushmarks on mine if you look really closely but this doesn't bother me.
when it's all dry, cut a piece of felt to fit the bottom of the box. coat the bottom with mod-podge and carefully lay the felt down. if you need to move it around do it fast because it sets pretty quickly and then you run the risk of ripping the felt. dab a little extra to make sure the corners stay down, but try not to get any glue on the outside part of the felt
and that's about it! i usually theme my boxes by country or stamp subject but you can do whatever suits your fancy!
