What are fuse beads?
Fuse beads are those fun little beads you put onto pegboards to create designs. Old video games and other pixel-based things are super easy to recreate using them because they work on the same idea of points of color. However, you can get even more detailed if you want to. The main thing is how big of bead you work with and how large a project you want to make.
