dd has been learning sewing at school & wants to sew a cushion cover. I thought I could make the cover or buy one & unpick the seam to open it out to make it easier for dd to sew. Thought about cutting out felt & then she could sew the design on. She's sewn with wool or thick cotton at school but I'm not sure what to get, thought fine wool would be easier to sew & if in a contrasting colour would look good on felt. Any ideas/advice?
