I remember Urban Outfitters in Cambridge in the early 80s. I also remember the Gap when all they sold were jeans and plaid flannel shirts!
The cotton canvas seat covers from Circa50 don't stretch over time. I think it has to do with the weight of the fabric. Canvas comes in several weights and the lighter ones wouldn't work as seat covers. I thought my home-sewn denim covers were heavy duty until I got the ones from Circa50.

I had quite the opposite experience and found both owners (Steve and Jeff) unprofessional and rude.
I placed three online orders dated 5/5, 5/15 and 5/23 for the Maraham Girard Quatrefoil Pink fabric pillows and was NEVER informed it was out of stock until further notice.
In addition, I was provided misinformation on 5/14 stating that the fabric would be in the following week. All communication was initiatiated by me to gather any information. In other words, Circa50 made no attempt to contact me at any time concerning any of my orders.
Circa50 offered no apologies for any of their business practices and have the attitude that they are doing customers a favor.
