I was looking up how to seal fabric paint when I came across instructions on how to actually MAKE fabric paint out of acrylic paint! I was like, "I spent over £100 on this for nothing?" I can't believe I'd never heard of this thing before!

Easily over £100 worth of paint. Scammage!

What it said was that you can mix equal quantities of glycerine and white vinegar, add the same amount of water on top, then mix in with acrylic paint until you get a honey-like consistency. Now I always knew you could dye fabric with acrylic paint without worrying about cracking (my acrylic stained pyjama bottoms are proof), but that was through merely diluting the acrylic with water, and I'd never tried actually painting on fabric, just dyeing.

Luckily, I already had both.

So I gave it a go. It made the paint very lumpy, but a lot of stirring later, I got a workable consistency. I got some fabric scraps, washed them with just detergent, then dried them with the iron. I then painted them with some white and caerulean homemade fabric paint. It did seem to bleed quite a bit on the polycotton fabric. I might have added to much homemade fabric medium.

I also did straight lemon acrylic as a test. Here's the crease test with that.

Then I folded the homemade fabric painted parts. I made sure to crease it well, and it held up!

I ended up buying fabric medium anyway. It's dirt cheap compared to fabric paint, £9.99 for 1 litre of the Scola brand, which seems to be the only brand widely available in the UK. Liquitex also has one, but it's tiny and mega expensive. I haven't tested the fabric medium yet, but if it works well for me, it'll save me loads of money!
