Welcome Back! So glad to see you back on the forum.
I've done some fabric printing and even wrote a newsletter tutorial on it several years ago. A lot of how well it works depends on your printer and the type of inks it uses. I've researched more than I've actually done, but it is something I'm interested in too.
I'll have to check out your tutorial, April. I have been working on some designs to be printed through Spoonflower. I'd rather have their workhorse professional fabric printers do the work than my printer on pre-treated fabrics (which seem to come out too stiff and with too many limitations). I hope to have something done in the next week and then I'll whip it into a handbag ~ what better way to combine my two loves?
