I have the same issue with my wife. She handles all business stuff, we have two homebase businesses. But, doesn't know too much about the technical stuff with leatherwork, (what tools do what, etc.) But, what drives me nuts is when I find my tools around the place (out of place) because she decided a particular tools would work great for X,Y,Z. Like using leaather shears to cut card board, etc. Oh My...But, I love her, so I just cringe and keep my mouth shut, then just remind her the cost of leather shears, (or whatever tool) versus the proper tool for what she needs.
