I'm new to leatherworking, having just done a couple simple projects at this point. I am working on my first stitching project with a speedy stitcher sewing awl. I am having trouble penetrating 2 layers of ~7oz veg tanned cowhide with it. I could get it through with quite some effort and a couple of small stab wounds, but I just broke the needle that came with it (which I believe is a #8) trying to push through again. I figure I am doing something wrong here. Any tips on technique? I've just been holding the leather in my hands and pushing the needle through. Thanks in advance!
