When I didn't have a space large enough to sandwich my quilts I could reserve a meeting room at the local public library and push a couple of tables together to do it there. I'd make a morning of it and invite a quilt friend or two to go along with me. Once I machine quilted a queen size quilt on my old Kenmore on my kitchen table in between feeding two little ones and keeping them occupied.
When I was attending quilt guild meetings regularly it seemd that many/most of the ladies had 'studios.' I quilted when and where I could and my supplies and stash migrated through the house according to the kid's needs for space and storage. Then one month a woman from England came and spoke to our guild. She had a picture of herself sewing at her teeny tiny kitchen table in her teeny tiny kitchen. From that point on I just pretended to be European whenever I started wanting a bigger space. LOL
