My midwife recently asked me if I would be interested in sewing a sling for her 16 month old daughter to carry her dolls. She gave me a few specifications and I went from there. Although custom work can be exhausting and cost much more than I charge (usually in hours designing and redesigning and fixing mistakes), I do love them. And I have learned to make more than one at a time so I can maximize my productivity and sell the extra.
