WHEW. I pinned this pattern months and months ago, but I'm glad I didn't try it until now. There's no way I would have had the patience to tackle some of these difficult steps until now. I want to try it again, because I want to do a better job with the piping. The tutorial for the wide-open zipper pencil case was interesting to follow, because the author used some different terminology than I was used to.
I had a tough time with the piping, because first I sewed too far away from it. I tried to fix it by sewing closer, and I sewed a little too close in a couple of spots. I think I have a better grasp on it now, so if I make another one I will certainly try to be a little more consistent. I'm definitely not using this cool pouch/case/whatever it's called for pencils -- I really don't have a lot of need for toting pencils around these days. It would make a kick-butt toiletry bag though.
