Wow -- they have an amazing selection of different leathers. Some of the larger pieces can be cut to whatever size you need (pricing is by the square foot); some are sold by the piece (no cutting down allowed); and there are tables in the front with scraps sold by the pound if you just need smaller pieces.
I was expecting plain leathers, but they had a wide range of different types, from bright colors, metallics, pearlized, holographic and sheepskins to embossed styles. There was even a piece with a lace pattern on one side!
Great customer service -- they were all very helpful and generous with their time. There were quite a few customers in the store when I was there, but it seems that their online business is robust as well. As a resource, they are best for one-of-a-kind items, as they often can't order additional quantity of a given piece. I ended up buying a scrap as a tester (perfect size for an obi-style belt!) as well as a super soft black piece for a jacket project I'm working on.
1. It is helpful to make sure you are buying a skin that is appropriate for your machine. Some leathers are soft and thin enough to be sewn on a regular home sewing machine, while others require an industrial machine.
2. A walking foot is essential. I've always heard about using a teflon or non-stick foot for sewing leather, but the store employees recommended a walking foot. I'm going to try this.
3. Fusibles can be used on leather. One employee mentioned a local accessories artisan who uses a double-sided fusible (with a press cloth) to attach lining fabric to the inside of a leather piece. Great idea, but I would definitely test this first on a scrap piece.
4. Always use a press cloth and a lower temp setting when ironing leather.
