It's really inexpensive to get started, especially if you can share the cost of a few tools between two or three people.
You'll need the following.
- A spool of thread: Campbell's satin-laid linen thread, for example.
- Two needles, but these are sold in packs... so buy a pack and share the cost with a friend.
- A block of beeswax, or a candle (a poor substitute, but it will do).
- An awl, lozenge profile is best, but round will do. You can make this for yourself from a scrap of steel (even an old nail will do).
- A sharp knife: a Stanley knife or even an pocket knife will do for your first small projects.
- Some way of marking the distance between stitch holes: a pricking wheel or some pricking irons would be the best, but a ruler or even a bit of thread with knots at regular intervals will do at a push.
- A small plank of wood to rest the leather on while you push the awl through it.
- A thimble, sailor's palm or a pair of pliers to help push the needle through the leather. You shouldn't need this, but at first you might find that you have trouble making the holes the right size, or that they seem to close up before you push the needle through...
For embossing decorative patterns or for making a groove for your stitches to lay below the level of the leather, you can make your own tools from hard, smooth wood (box, hornbeam, holly), antler or bone (save the shin bones when you make stew). You could even have a go at making your own needles from bone, and use sinew for stitching, but I'm sure there are other people here on BCUK who can explain that side of the craft.
