Only I didn't have exactly what I needed on hand...
Of the million things you will find to make enamel dots from when you do a search on Pinterest- mine does not seem to be listed. You see perler beads seem to work fine, and what I had were just really big versions of perler beads (My First Hama Maxi Beads). I liked the idea of really big fun dots, so I decided to give it a go.
Then I played around with a medium sized bead I found at Michaels made by Creatology that was labeled as a pony bead, but just looked like a medium straight sided perler bead. **( This is also where I discovered that foil is not the best choice for baking, as the beads were hard to remove).
Then of course I made a ton of tiny beads from real perler beads this time using an old heat resistant splat mat in lieu of foil.
...then I discovered I could place a small perler inside the center of the medium bead and make duo tone dots!!
Here's a little breakdown of the sizes achieved from each bead:
I've also read tips that you can cut the beads in half to get yet another size variation.
I'm all set now, and have already used these on several projects. Unfortunately my kids might have to find a new favorite craft since I've acquired their supplies!
