These bad boys need to dry thoroughly before we go any further. Leave them over night if you can — or at least a few hours till the paint has all sunk into the canvas.
When they’re properly dry, you’ll need to set the fabric paint. Check the instructions on your textile medium on how to do this. For mine I need to set the paint by ironing it. That’s right, I ironed my shoes! (ticking off of bucket list) I’d advise placing a tea towel over the top of the shoes before ironing them, just to make sure it runs over smoothly. It’ll only need a few seconds to heat them and I did this by holding the shoes from the inside. Just make sure you don’t iron the soles or they might melt!
