Once again, I'm going to start with Rio Rondo (http://www.riorondo.com/). This is simply the most complete source for all kinds of hobby goodies. In addition to the kits we discussed last time, Rio Rondo also carries all kinds of leather and leatherwork supplies as well as a dizzying array of model hardware. I particularly like the shiny, photo-etched buckles, d-rings and halter and saddle plates.Rio Rondo's online order form is easy to use and their customer service is consistently good. They do charge a small order fee for orders less than $10, but that is never a problem for me. I tend to buy in bulk so I am far more likely to qualify for free shipping (orders over $100)!
The second stop on my tour of favorite suppliers is The World of Model Horse Collecting (http://stores.shop.ebay.com/The-World-of-Model-Horse-Collecting__W0QQ_armrsZ1). This eBay shop is owned by Alison Bennish and is chock full of all kinds of hobby hardware. Alison's bits and stirrups are my absolute favorites. In general, her castings are very clean and need little to no clean up before use. Alison's shipping rates are very affordable, so this is the place to go if you only need one small item.
I use a lot of leather lace and without a doubt, my favorite lace supplier is Melody Snow (http://www.unicornwoman.com/ ). Not only is Melody's lace superior in quality, it's also available in a wide selection of colors and widths. I especially like the Brandy color which is shown below.
Aside from lace, the two types of leather I use the most are Petite Tooling Calf and Sheepskin Skiver. I buy these by the hide at my local Leather Factory (http://www.tandyleatherfactory.com/ ) store. Unfortunately, the Leather Factory has discontinued the skiver hides. I stocked up before they were gone and still have about half a hide left. I'm not sure what I'll do when I get to the end of it. Suggestions on this are gladly welcomed!Of course, leather isn't the only thing you can buy at the Leather Factory. I also buy all my dyes there as well as all sorts of leather working tools.Micro Mark (http://www.micromark.com/) is a wonderful source of small scale tools. The three piece pounce wheel set is of one of the most helpful tools a model tackmaker can have in her arsenal. I use the smallest wheel to add the "stitch marks" to my tack. It's a wonderfully easy way to give your tack that little extra bit of flare!
If you like bling (and who doesn't?), be sure to check out this site: http://www.crafts2do.com/ . They carry all kinds of small scale decorations that work wonderfully on model tack. This breast collar by Erin Corbett has three different types of Crafts 2 Do findings: nailheads, teardrops, and medallions. Don't forget your local hobby and craft shops. Even with so many great online offerings, I still do get in my car and drive to Hobby Lobby on a regular basis. It's a great place to buy fabrics, thread, ribbon, embroidery floss, glue, wire, small tools and all sorts of jewelry making supplies. Here is a small selection of things I've bought at my neighborhood store.
