I don't believe it is possible to make your own gloves, sorry. Are you needing gloves for training or are you wanting them to use on a heavy bag or ...... ? If for training then purchasing the right gloves will be an investment that you should not skimp on. If for fooling around with buddies then I would suggest don't waste your time. If for a heavy bag then I would perhaps suggest some light boxing gloves and if that can't be afforded, purchase some cheap light leather gloves/mitts which will at least help with tearing of the flesh. For some of our drills on bags and focus mitts we use light leather mitts which work well.
