Yes, I totally agree with the majority here: do not skimp on the quality of the paint.
Yeah, you'll pay more, but you will get better results.
Acrylic paints do work best with original Megos, and the color selection has really grown, so you can often pick just the color you need & paint straight from the bottle without having to mix! And Acrylics are easy cleanup, too: water!
Oh, and be prepared to spend time in fabric shops!
I think you are really going to enjoy this hobby!
