When I first saw the press-n-seal I thought that surely it had quilting applications. Then I remembered an episode of Simply Quilts where a lady used masking tape to "pound" flowers onto fabric. I think I'll give that a try come springtime.
As a long arm quilter, I use the glad press and seal to repeat my designs on a quilt.
For example, if I want to make sure feathers are a match, and I don't have a stencil, I trace what I had done on to the glad wrap, and stick it to the next area I want to quilt an exact repeat.
since I am not perfect...and no matter how careful I am in piecing and then sandwiching the quilt. sometimes I have little pockets of more quilt top than bottom....my husband calls them "puckers" such an ugly term. I prefer to call them "extra warmth".
I guess anyone who's seen the handi-quilter set-up video already knows this...but glad press n seal makes a great quilting design marking tool. use a washable marker to trace your design and then simply smooth it onto your quilt top. it helps to stabilize any areas of "extra warmth" too. the only con is having to pick out the stuff from your stitches, but a dip and spin in the washing machine will help.
