You are definitely not alone on this one! I asked my IT person (my 11 yr. old son!) and he recommended that we try starting with the paint command in Windows (accessories, then paint) and try creating simple designs that way. Or, if you have a scanner, you can draw something freehand, scan it, and edit the document with the edit program on your scanner. All this from someone who can work a computer but not a manual can opener!
Technology, huh?!!!! Anyway, please let me know if this helps you and I'll keep you in mind if I come across any other ideas/software.
