Sizing Guide & Adjustable Tools for Custom-Fit Hand Chain Jewelry

New jewelry makers often find it challenging to measure and size hand chain jewelry for different hand sizes. A comprehensive resource, like a guide or video course on measuring techniques, standard sizing charts, and creating adjustable designs, could be really helpful. Pairing this with physical tools such as an adjustable hand mandrel or sizing templates would make it even more effective. This would not only solve the problem but also boost sales of the guide, tools, or a combined kit, helping new crafters get better results.
