Does anyone know of any craft stores in / around Aachen Germany or Sittard NL?

I'm looking specifically for the tape (Grosgrain, transparent, glossy), glitter, glue, fabric, acrylic strass, etc.

In Aachen, try Listmann (near the main Mayersche) and close cooperative shop Karman Auditorium. You should check out the fabric store in Groß Kölnstraße, opposite Müller, who are moving and have all their stuff on sale. (but I think only until the end of this month). Maybe you can even find some cheap wool or one of Kaufhof stores 1 € at the end of nearly Adalbertstraße to Kaiserplatz who have everything (at least sometimes). Or you could check one of the fleamarkets, there is one every Saturday inside Liebigstraße and I think all Sunday is a Melan somewhere (just Google and have all the dates of your page).
