I searched for Swiss quilters using the search function and find that there are full paid members and some who use the free option. Unfortunately only a very few of the members add photos of themselves, their quilts, or other profile information.
I encourage my fellow quilters in Switzerland to share their wonderful work with the TQS community. I know you're out there because my local quilt guild, Patchwork du Leman, has over 50 members and there are many other active guilds. The national quilt association is patCHquilt. Don't be shy to post in your native language.
There are translation sites (Google Translate) that do a pretty good job. Hey, my French is pretty bad but I go to the meetings and activities and my fellow quilters are a pretty tolerant bunch. Quilting is a universal language!
