hi, you could use Embird Basic, it is free for 30 days, I have it and is a very good, affordable embroidery software If you go to Embird site you can download and read about it.
I use a lot of thier Applique designs and they resize very well I do mine through Embird good luck you will love them Hugs Shazells
