I tried to remember what my mum had in her sewing kit and bought few things, scissors for material, pins, pin cusion, measuring tape, dressmaker pencils, unpicker (for those stuff-ups!), needle and thread.
When I bought my machine I was lucky to get a sewing book in there that explains lots different things which was great cause I had no idea of all these sewing terms on patterns.
I'm still looking for a sewing class to join.
