If you don’t send thank-you notes, then shame on you. If you do, then you should know about Silas Tom. The new company started by Dallas designer and illustrator Rob Wilson specializes in greeting cards of every kind. There are holiday cards, birthday cards, baby cards, and more. They’re all bright and bold and unique, but I especially love the “Thank You Writer” cards. Spelling out “Thank you so much” on typewriter keys? So clever! Now I just need someone to buy me something nice so I can send the proper thanks.
