Not I. I was busy sewing, eh, other things. Things I'm still using cuz there's still so many eejits out there. BUT, don't wait for motivation. Create success. As out in my shop, I often start with a mock up. We all now have lots of cardboard boxes so mock up the tool roll with cardboard. Check for size, adjust, make another one. Scissors, tape and glue and your on your way. Use the mock up to think about the pieces you'll cut and the assembly sequence. Be willing to fail because each failure is cheap and teaches you things.

Then take an old shirt or torn pair of jeans (only the knees are torn, the rest is pretty good material) and make a "test article". Plan to throw it away so it need not be well done but is valuable practice. Fit it on the bike. Adjust and replan. When you're ready make the "ops article" with the material you've been saving.

Hint: if you're planning to attach straps or grommets or buckles, plan how and when you'll do that. I find its often easier to attach such things before I sew the pieces together. Also plan ahead on how you'll seal the material edges. Folded seams, glue, heat, etc. Again, where and when.

Each step will teach you something and be a success. That's motivation, eh.
