When I was a kid, six years or so, I loved making necklaces and stuff out of hamabeads. Some were glued onto pieces of wood and used as saucepan mats or wall decorations. Tacky, I know, but I guess my mum liked them even tho they were ugly :) I remember I had pegboards in shapes of butterflies, hearts, stars, animals, squares and circles. Some needed ironing or glue and some were done immediately. I still loved it. When I got older I tried to make nice earrings, bracelets and necklaces but I was never satisfied with the result.
Now I’m back with the pegboards and enjoy the pixel-like art I can make. Mostly well known figures such as Bub & Bob from NES or a KoopaTroopa on request by my brother. I also made the warlock class icon from World of Warcraft (the trickiest so far) and the Commodore logo for a friend.
Not sure what kind of function they have, but using them as table protection (for glasses and saucepans etc) should work fine. As these are better looking than the ones I made in my early days I might even use them as decorations ;)
