I spend time practicing knots from time to time too so you're not alone, but I'm not saying we aren't a little crazy. An idea if you wanna tie though, pick a pattern you want a bunch of, either one you wanna learn or one you use a lot, get only the tools and materials you'll need for that fly and go set up on another table in the house to tie. If you're only tying up a dozen or so of one pattern, unless they involve spun deer hair, the mess should be pretty manageable and you get to focus on getting that one patter right without the distraction of having access to all your other materials to substitute or alter the pattern. I did this with some size 18 pheasant tail nymphs and hairs ear nymphs. They are still the only fly pattern I can think of that I have close to a dozen of the same size/color on hand. Everything else I tie maybe 3 or so and get bored and move on to something else or try something a little different. Just a thought for when the knots start to get boring.
