So if you've ever been to a fabric store in the US you will notice their minky selection is pretty limited unless you want it to have this annoying pattern on it. I dont know who this is for or why its like this but unfortunately thats the world we live in. Here is how we remove the dots in a pinch.
1. place the minky on a flat suface (an ironing board) and heat the iron to max for synthetic fibers.
2. put down either a cotton shirt or we are using a sew on interface here as like a shield. Iron over top of the backing of the minky first
3. Then flip it over and put your cover over the good side of the minky and repeat untill your dots start to fade.
Make sure to sniff for any burning and to trust your instincts and work safely! Better results can also be achieved with a steamer.
