The pes will rotate to 'just' fit in my 4x4 hoop. Otherwise try resizing it, it will only cost you a little time and thread to try it out.
I would also download the snail design. I use Embird and was told 20% up or down is doable. I would try to resize it and try a test run with stiching it out. HTH
I can't answer your question, have never tried to resize applique. Why don't you go ahead and dl the snail, that way you'll have it and hopefully someone will be along to answer. Hugs..Carol
