I am a little late making Halloween bags as it was a long summer but I have three done, three half way there, three cut and three that have fabric pulled. Here is the first batch.

I love, love, love this fabric. The horizontal stripe of the focus fabric with the coordinating stripe for the interior is very sharp and makes the interior of the bag just as much fun as the exterior.

I have three done and hope they are a hit at the craft show in Ridgewood tomorrow.
