A fun little box if goodies. You can get spinning right away! You do have to attach the handles to the carders with a screw. The handle is drilled, the top of the carders aren’t. Rubbing the screws on a candle before help them go in like butter. Unfortunately none of the roving or un-carded samples are labeled, so mix and match and have fun! I’d look up some YouTube videos on spinning silk before using that part of the kit. I want a wheel next! Great kit, highly recommended.
