One of the things I love to do is create with junk. I've made lots of different things and you can see most of them here on the blog. It's hard to not just discouraged from creating junk projects though because they do not sell for me locally, they never have. I am sharing 4 butterflies and dragonflies I made from various pieces of junk and scrap wood, 100% repurposed.
When possible I use screws to attach the junk, other times I have to use a combination of glue and wire.
