If you were as inspired as I was by Luke Deverell’s work over at Darn & Dusted, Reddit member AnalogDimitri has a pretty nice guide on how you can learn to hand darn something yourself. Tools you’ll need: some scissors, heavy sewing needles (maybe some darning needles), and heavy thread (such as topstitching thread). You can buy these supplies at Amazon or Wawak, although I recommend just going to your local sewing supplies store.
Note, when you get to the image gallery, you may have to click the “load entire album” link at the bottom in order to see everything. The guide is pretty thorough, so there’s a lot of stuff here.
