All wonderful creative ideas ladies {sorry if i missed a Gents reply}, I too swiped the lg T square from hubby's workshop right along w/ a very nice Stanley 3 tiered nuts & bolt container to hold all the different feet for all my machines, it originally intrigued me because it matched the sewing rm colors..lol and he let it sit empty for way to long.
I hang a small paint brush from my desk lamp for cleaning the bobbin area & couldn't live w/o long tweezers.
