i can understand using a computer program if you have computerized machines that run off cad programs to cut patterns and such but for the hobbyist or one man shop its just more time and money investment, especially for wallets , card holders and such once you've made the pattern there just isn't a need IMO. it may take an hour to make a card holder pattern by hand then you have it forever, scan it save it and print it whenever if your old one wears out. I'm of the age that i have learned every darned operating system including dos bought thousands of dollars worth of computers operating systems and programs that are/were setting in my basement because they are no longer "supported" meaning they just want to make more money off of us not that they weren't adequate. Just hauled a milk crate completely full of floppy discs and old cds of programs that no longer work to the dumps, INCLUDING a couple expensive autocad programs But to each his own folks spend that money, take that time learning a program you will have to relearn at the next update or simply repurchase because its unsupported while i use my pencil , and paper template and do leather work. Me, i like simple!
