I'm going to give skin systems a try. I've used Swiss Lace systems for the last 3 years or so since I started wearing hair systems. I'll have to trim the base of the skin system to the size of my template since I'm going to try a stock system. I've done this with lace systems where I use sewing pins to pin the system upside down onto a mannequin head and then cut round my template using small scissors to resize the base. However, is the method the same when resizing skin systems? Will it harm the skin base if you pin it down (I'm thinking, it'll make little holes in the skin base, whereas it doesn't matter so much with lace as it's already got holes in it and it's more durable than skin). So what's the best way to resize a skin system?
