well i got fairly big mitts, so i'm given to larger grab bars and handles and usually the XL gloves in the hardware store. Still there's always room to try that out, even if the turkey needs immediate internal temperature reading and your thermometer is buried deep inside drawer number 2. what size handle does that mean?
Here are 3 tries: 3" 3,1/2" and 4" long.
The bigger one might be most appropriate for something like a pantry or laundry door. Too big for smaller drawers.
I also think how these things are finished will affect the feel a lot. I've just got 'em sanded to 120grit. but imagine if they had a lot of poly on them. Then there's the other idea of using a hard wood like maple, or mesquite. Also, have to consider painting these, which could be really cool little dollups of color on a natural wood panel finish...
