The computer program to digitize stuff is $98 a year and you need an internet connection to use the program. >-> That's pretty much all you need to make the patterns. Of course there's quite a learning curve for using the program lol. I use SEU and I've been using it for over a year now and I'm still finding new things in the program that I didn't realize I could do.
My embroidery machine is nice because I just plug in the USB cable into the machine and my computer and it's like using a jump drive. Just drag and drop the embroidery files. (It was $350 for the embroidery machine though....+ materials and stuff, I can't even begin to tell you have much I've spent on embroidery materials.)
I'm going to have a special Black Friday sale that lasts all weekend and it's 25% off all patches :3
