Sorry, no experience with yarn, but doing the honey do's is an important part of this hobby. If you can manage to make one or two usefull things for the missus it goes a long way to gain support for your hobby and the possibility of buying new or bigger equipment. I know mine appreciates the little gadgets and widgets I make for her from time to time. She is always positive when I discuss buying some new tool or machine. All she asks is how I plan to pay and does it fit the budget,. Otherwise she has never put her .02 in as a negative comment. I make her yard art, garden boarder edging on the plasma table and a really cool fire ring to go around the pit. It casts some cool shadows in the evening light. The fire keep the mosquitos busy and is a nice thing to sit around and look through the telescope at the different galaxies and heavenly bodies. Definately improves the over all good relations in every way. Hope this helps get you and the rest on board for a "Momma Build" as youre next projects.
