My husband also helps out on the math that I'm frequently stumped with. He is a carpenter, so figuring out angles, yardage, he's a wiz. I was having a big problem deciding on a wide boarder for a quilt this winter. I had two fabric choices and asked his opinion. Against my better judgment, I went with his choice and this time, he was so right about it!
My husband has designed and made several ice fishing tents. Makes his own patterns, rotary cuts and sews them. He's done a great job.
