Not in any way to squash the do it yourself plan, but if you want to make a trad set of shoes winter may be almost over by the time they are done, assuming you have to work during the week.
I think making them yourself is a great idea, but just know it might take longer than you think. Using synthetic webbing will make quite a diiference in time. Don't cut corners on wood selection- go to a yard that has green ash available. Avoid KD or even drryed wood if you can. Easier to work the new wood.
I don't have a plan recomendation- I designed my own.
