I quilt for others, but not alot. I know alot of local quilters to me have regular pick up/drop off times at a quilt shop. You need to check wtih the shop before you set this up. However, it has been my observation , that unless the shop has a long arm IN it, they are happy for you to bring your customers into their shop. They get more business that way too. I don't have enough clients to justify a store front, but then I don't want to quilt that much. You might try asking over on machine quilters resource.
www.mqresource.com Lots of full time long armers over there.
