While that dried, I cut out letters with my cricut using the Jasmine cartridge. You could use vinyl letters as well, but since I was going to mount this on scrapbook paper anyways, it just made sense to use paper.
You can see that the paper is bubbling here. That is just because it hasn’t dried completely. It was completely smooth when it dried.
Since I was using galvanized steel, it would be impossible to just hammer in my tacks. I pre-drilled the holes, then used tacks (found at Lowe’s. A box for .99) to attach the steel. I love the copper ones against the steel.
