I was looking to do a bit of customization on a kilt of mine and was wondering if I could get some tips from the pros. I really want to do a red, raised fist on the apron of my kilt, and I was thinking of just using a red Poly Cotton (same type as kilt) then just sewing it on. My question is what method should I use to create the definition lines to form the fingers? I am really new to sewing (can hardly do buttons) so I don't really know any techniques.
