Reddit mentions of FolkArt Enamel Glass & Ceramic Paint in Assorted Colors (2 oz), 4032, Licorice

Have you considered getting a plain piece of glass, tracing the borders onto the new glass and hand painting a new frame? Your mom would like it even more because you did it by hand, even if your painting is a little uneven. Use a sharpie or "china pencil" to trace the design, then something like this

to paint the "frame" onto the glass.

Alternatively, you could get some black poster board and cut out the squares where the pictures are, maybe using tracing paper to get the layout of the frame.

I am in the middle of doing this, and plan to do a tutorial when I am through. I have a few tips.

• Because glass is so smooth, paint your first layer of paint using a "glass medium" paint like this. This step is a pain in the ass, I admit, but I think it makes a big difference. This is a paint especially for glass, and should not scratch off. My concern was that one of the boards would get nicked, and the paint could come off and look like a scratch. The glass medium should help avoid that and will help your chalkboard paint stick. The glass medium needs to "cure" to be effective. To cure your glass you either: (A) bake smaller glass panes in your oven based on the instructions on the bottle, I reccomend putting them on a cookie sheet or (B) Let them cure for 21 days (omg, so long, I know!) I have 3 huge glass frames sitting in our dining room with 13 more days to go.
  
  
• I am concerned about the glass breaking during transport, especially for the larger pieces. You can pack them as best as possible, but they still may break. I recommend covering the back of the glass, the side you won't see, with painters tape or masking tape. This way if the glass does break, you don't wind up with shattered glass everywhere.
  
  
• Use a foam brush or a foam roller for your chalkboard paint. I think this is the best chalkboard paint. I've used others in the past, and this is far superior in terms of the finish, coverage, and texture. The spray paint versions flake off easily and don't always come out smooth because it can drip sooo easily.
  
  
• Also regarding breaking, you can add some padding to the back of the glass by just putting a slice of cardboard the size of the glass behind it.
  
  
• Chalkboard pens are the best! Don't use regular chalk to write, but you can use it to give your fresh chalkboard paint a more realistic look by rubbing chalk all over your painted glass, then "erasing" it with a dry cloth or chalk eraser.
