Yes, you can buy one online, but how about Doing It Yourself and having some fun? Well, let's start!
Step 1: Materials
- any frame that you like
- and GITD window paint (any kind will work)
Total cost for me was about 3€.
Be creative, you can use literally ANY frame of ANY size...
Step 2: Secure the Back Side
Step 3: Start Applying the Paint
Step 4: Level It
When you are done, let it to dry (this takes about 8-10 hours)
Step 5: Clean It Up
Once it's dry, remove the glass from the frame, clean the frame from any leftover paint and put the glass back in. I recommend to put it in with the paint side facing inside, so it will be easy to clean from dust etc.
