I was reading some of the posted comments, and had a wee-bit of information to contribute.
Regarding the Glad Press 'n Seal technique Amy used in the Halloweenies: I haven't done it myself. However, I did watch her use the technique during DVD #5, Fancy Flowers. Amy used the Glad Press 'n Seal during her Appliquéd Felt method for Flower #1. Perhaps reviewing the DVD might further help with the Halloweenies Stitch Guide? Just pop the DVD into your computer, and advance to the Glad Press 'n Seal Demo for a quick look-see.
I looked up Glad Press 'n Seal on the Glad website, and it does seem to be available in both USA and Canada. Here's a photo to help you find it in your grocery store.
Well, hope that helps. Thanks, Robin
