Quetion about monograms/DIY

HELP: I wanted to have some fun and try designing my own monograms. I'm going to go buy a program tonight and have no idea which one to buy. Any suggestions????

Also, do you go to cinkos to have tags and stuff printed out or do you diy?????

Please help!

I don't know if you need to go out and buy a program. I just made mine in Word.

Good luck!!
I'm sure it will look great.
