Check out this chic rubber stamp as an alternative to illegible script. Primele Studio on Etsy that run $64 each.
And another one, Paper Finger, who offers 8 different calligraphy styles to choose from at $65 a pop. I spotted this a few days ago at Gap's Cool Hunting Shop on Fifth Avenue when hitting the Amy Sedaris book signing for her latest (hilarious) book.
One of my favorite stationery shops is Rock Paper Scissors based in lovely Franklin, Tn. They sell a great rubber stamp for only $28. Check'em out
And they come in a cool modern font like this...
I had one of these made when I moved a few years ago from Kate's Paperie. One word of advise from a gal who messed up one too many envelopes, practice using your stamp and use a well inked pad. You just need a few dry runs to make a pretty stamp.
ps. Thanks, Dewine, for the inspiration!
