I found some similar Christmas Decorations on Amazon for my Northern Hemisphere viewers!

If you’re in the Northern Hemisphere and you can’t get the Kmart kits, I linked this as a similar “paint your own” Christmas ornament option on Amazon. I haven’t tested this exact set myself, but it looks like the same kind of project—unpainted ornaments you can customise at home. It’s a good starting point if you just want something fun to decorate and seal.
