I recently accepted a job making a quilt out of embroidered blocks of the birds of our 50 states. Blocks were 9-10" sq.,and I found a simple pattern with sashing and one boarder. I told my customer I would charge $10 per hour for my time, which I would keep track of. I took her shopping, and she paid for the fabric for sashing, boarders, and backing...about $75 at Joanns.
The finished size was 92" by 118", and I had to buy a walking foot for my Grand Quilter, cause I didn't want to try anything that big on my regular Pfaff. I ended up charging her $300, and I left out some hours in hand sewing the binding, cause it was getting so pricy. If you never kept track, it is an eyeopener.
