Designing a dual yarn holder: Need your expert advice on base stability! (Deep pit vs. Shallow base)
Hi everyone! I'm currently designing a premium wooden dual-spindle yarn holder, and I want to make sure I get the mechanics absolutely right before I start making prototypes. I’d love to get feedback from actual knitters who use these tools daily.
I'm torn between two base designs regarding the spindle seating (see the attached photo):
Left Image (Deep Recess): The spindle sits deeply inside a carved-out bowl in the base. My thought is that the wooden walls will completely stop the spindle from tipping over when you yank the yarn from the side. But it requires a much thicker, chunkier base.
Right Image (Shallow Base): The spindle sits on a very shallow plate. It looks much sleeker, modern, and saves space, but my biggest fear is that it will easily fly out or tip over when pulling yarn at higher speeds or weird angles.
My questions for you:
- Does the deep pit (Left) actually make a huge difference in stability in your experience, or is a heavy shallow base (Right) totally fine?
- Has tipping/wobbling been a major pain point for you with wooden yarn holders?
- Bonus question: I'm planning to make the spindles interchangeable (screw on) so you can swap a thick wooden spindle for a thin brass rod for yarn cakes with tiny center holes. Would you find that useful?
I really want to design a tool that is highly functional and makes a great gift, rather than just another pretty decorative piece that doesn't work well. Any brutal honesty is welcome! Thank you!
