So yeah, I know this isn't a toy. But kiddos with tubes love pretty pads instead of ugly, white gauze ones. Surprise your tubie kid with a stack of these!
1. Trace circles onto flannel or any other absorbent fabric. I prefer flannel because it doesn't stretch much when you sew and it's nice and soft. I use 3 layers in my pads and I use the same cup every time so they are all uniform.
2. Pin the layers together and draw a small circle in the center and a line straight down. I use regular kid's washable markers and it washes out in the first wash.
5. Zig-zag around the edge of the pad. Go slowly and reposition the foot as needed. Because it's so small you really have to stop and start a lot unless you are just a genius with a machine (I am not). After zig-zagging, do a straight stitch around the whole thing for added stability.
7. Add a snap. If you don't have a press or snap pliers, the metal hammer on snaps work fine. They are a bit of a pain, and take a little practice, but they are cheap.
The hand-sewn version: Do everything through step 4 and then just stitch by hand instead of using a machine. It takes longer, but it actually looks nicer and neater, especially around the small inner hole. I used 2 layers of thread, but only 1 is really needed. Wrap the thread around the edge and then straight stitch all the way around. One pad took me an hour vs 10-15 minutes on a machine, so it's not all that time consuming. Stitch one up while you watch your sitcoms in the evening!
