when i started researching this several years ago, the average rate i read was $15 per hour. i wouldn't hesitate to charge $20 per hour - plus supplies. supplies include but are not limited to fabrics, batting, needles, thread and rotary blades. if embroidery is involved add the cost of stabilizers.
of course, that formula doesn't work for me. i'm pretty methodical and meticulous which slows me down. if i charged by the hour, i couldn't sell a placemat for under $100. somehow, i don't think i'd get many customers. :lol:
i just look at the quilt in my imagination and pick an arbitrary price that feels right.
