P E Basic is a Brother software that consists of the card reader/writer & blank card that only works with .pes designs---which is your format with Brother machine. You install the software from CD, and access your designs on the computer, where you select and send to the card. Each time you write new designs, the card erases (but your computer still has the designs) You can also size up or down about 20% in the program. You can find it on Amazon, Walmart (on line), at Allbrands, and be sure to ck ebay. The cost will fluctuate--I've pd $80 on ebay, $105 at Walmart (if I sold a machine, I included the software when needed.) There is a very cheap program for merging .pes designs that would be useful for creating monograms--it's called CombineDsign at www.bowsandclothes.com. If you have digitized fonts (there are many free) you can merge into monogram with this program. There is a youtube showing how to use it. You first need to get the software for moving from computer to machine. Good luck--hope I've helped.
