Had so much fun making them! ---> Time limit includes drying time.
If anyone's interested, I pretty much took the instructions of the space shoes and then played around with it. For starters, I only had black canvas shoes, and I included spray paint which will make the design last a lot longer, and gives it a little shimmer - perfect for a galaxy!
I took a lid, sprayed a large amount of a bluey-teal paint onto it (so it became just like a blob of paint) , and then included a little white acrylic to help it stand out from the black. After brushing that on, I added more white for a lighter blue, and then added red to the spray paint (to make purple) and some white to make lighter purple, using the same dry brush method. And after the shoes were done, I added a sparkle of silver spray paint, and a bit of gloss varnish just to give it a finished look!
