Needle falls out when stippling
You can tell by the problem that I am a Newbie to stippling, but I am giving it a go! I think the needle is on correctly and it feels tight, but after stippling awhile, it fall out. Aside from trying to tighten it more, any tips? Also the actual darning device is plastic and it falls off the screw area where it sits. This makes me wonder if it is on correctly, so here is the photo. Thank you!
