This video explains the difference between using BX and PES when working with Applique Alphas. Because these are Appliques and not Embroidery Fonts you are limited in how you can use them with BX. Now you will be able to decide if you need BX or PES (any format) to make your edits to your design. ENJOY! Feel free to email me at Teresa@babykaysappliques.com if you have any more questions about this.
