To Longbyt: Thanks for relocating my post. I had the hardest time deciding where to put it. ;-)
To EastEnders: Thanks for helping me with my search. I found that German word along with "Knüpfgarn", "Knüpfpackungen" and "Schnittpackung."
Googleing, I ran across some eBay and ricardo auctions, but they didn't have the colors I need. Some other sites only offered complete kits.
As you suggested, I will also check my local Coop and Migro DIY. However, during my search I did not run across any shops in the Baar/Zug area. Would you please tell me the names of the craft shops you found? I live in Cham.
Thanks again for your help.
