So once you've finished all that stitching you should be left with something like this - a freezer paper shape tacked onto your background fabric with just a hint of the applique fabric showing at the edges :o)
Then take out the tacking stitches, peel off the freezer paper and ............VOILA ! ! ! !
And of course the added bonus is you can reuse the freezer paper shape again and again and again!
So .......what are you waiting for - dig out some freezer paper and have a go :o)
