Easy way... draw around pattern piece in wax crayon, place pattern paper wax side down on top of pattern piece on ironing board. Switch steam OFF on iron! (I forgot this on the 1st one!)
It transfers the pattern quickly & perfectly!
Here I have traced around the right pattern piece in green crayon
If I had remembered to switch off the steam there would not be crinkles on the green one!
But it took all of 2 minutes!
PS. I bought my paper here
