I used vellum when I did fabric painting.
You could copy a design (backwards) onto the vellum using a "toner" copier then use it as an iron pattern to paint over.
You could iron it several times from the one copy.
Vellum worked really good for that (be ware, the toner did not wash out...it was an "outline" that was painted over" so it didn't matter for those projects.
That is a super low price.
