I used DK-weight yarn to make these fun soccasins. I ran into some tight spots, but the designer was quick to respond and very helpful. A couple of years ago, she gave me permission to videotape a tutorial, but soon after, we had a tragedy in the family; so it was put to the side. I plan to soon start a pictorial on my blog. I want to try making them with worsted-weight yarn to see what size I end up with.
