I'll work on this tomorrow, I have been reorganizing all of my supplies and household goods in preparation of a move in the near future. Sorry about the delays everyone.
If you would like to get to work on the project it is a good time to order what you will be needing to actually construct your shoes.
I recommend these items, but you can use your own things of course. For what it's worth, if you have a hobby lobby nearby, check it out. It's a great store to buy this stuff in for a lower price for the most part. I bought my roll of sinew, needles, and the thonging chisel there. Better yet, borrow the stuff you need unless you plan on doing this often. I don't make shoes or work with leather much since it's a bit challenging at times, but I keep stuff on hand for when I do.
The materials used will be 5-6 oz 'side' leather. Don't get splits or suede. They'll work I'm sure, but the shoes won't be so durable. As far as the size goes, I bought something on Ebay that was cheap. I'd suggest doing the same as I did. Anyway, the size. I bought a split that was 48" by 18" at the largest point and 12" at the thinnest point, so I think you'll want something around that size depending on your feet. Seems like about everyone measures the leather size differently for some reason, so it might be worth waiting on the leather purchase until you have your pattern.
Buy or hijack a cheap pair of socks from somewhere; you'll tear these up when making your pattern, so don't stress over getting something nice at all.
A roll of duck tape is necessary as well for pattern making. Don't try to use any other type of tape. I did this with masking tape once and it was a nightmare... it kept pulling apart and I ended up ruining a pattern, so stick with duck tape!
Last thing you'll need is a sharpie or any other marker.
We'll make the patterns for the shoes tomorrow so you can see what you'll be doing. It's easy, you can do it!
