I found a tutorial at "A Lemon Squeezy Home" for an adorable shirred dress. I love the effect of shirring, but it was such a challenge with my old machine that I had given up. Luckily, it is super easy with my new machine (even though it has a drop in bobbin-check here for tips on dealing with that) I wound my bobbin both by hand and by machine, and didn't notice a difference in either. My problem was getting the bobbin thread up out of the casing.
It is a super easy tutorial to follow. She even includes a great link on shirring, in case you're nervous about trying. (don't be!)
All told, this didn't take me long-a few hours (but with kids, that is probably 1 hour kid-free time) I love the idea of adding details to the dress, especially if you have a simple solid color. The hardest part was measuring Zgirl. She kept wanting to play with the measuring tape =)
