Every fabric in the shop is one I have washed, dried, and handled myself before it gets cut.
Corduroy, broadcloth, and soft cottons are my staples. They hold a shape, feel good on sensitive skin, and come out of the dryer looking like themselves.
Notions matter just as much. Wooden buttons, smooth elastic, and lace that does not scratch make the difference between a piece that gets worn and one that gets avoided.
If I would not sew it for my own family, it does not go on the rack.
