The website is now defunct but the chart can be found here. I used 14ct Aida fabric. Nowadays, I'd use some type of evenweave fabric.
Today, I made a black cord, stuffed the humbug, and stitched it closed.
I keep plugging away on my office/craft room in hopes I can get it somewhat organized so I can find things easier. As such, I continue to unearth UFOs, many of which can be finished in under an hour.
