Debbie, They are very cute!!
I just dug out my son's Halloween costume from his second Birthday/Halloween party. I made his costume---he was a lovable scarecrow. I'm going to make it work for my DD this year.

Thanks goodness for the glue gun!

There are a few "stitches" on the outside that should be there but other than that, everything is hot glued.
She was about the same size as him except she's not as tall--well, she is about 6 months behind him when wearing this.
Ill try to get her to wear the straw hat long enough to take her picture, lol!! She LOVES the camera so it might work!
My son wasnt in the creative mood this year so he will be wearing a store bought Hulk costume.
Your kids are soooo lucky that they have a Mom who is "sew" talented!!!
