WOW, am I impressed!!! I would like to do something similar but I don't have any experience with tools. DH might help but it rings too much of a "honey do", which aren't his favorite thing.
I bought a used sewing cabinet but my new machine is too large and heavy. I'm not sure if I started cutting it up everything would work. I don't think the laminate cabinets can do as well as real wood.
You go girl!!!!!!!!!!!!
