A friend recently showed me the site, Via Letter and I happen to think it is one of the most brilliant ideas ever. I love to receive letters in the mail but actual 3-dimensional letters take it to another level. The site is really easy to navigate, you pick out your letters, font and packaging and then it is sent off to a very lucky person. The letters range from $3 - $5, a bit pricey for a long word or sentence and that doesn't include shipping (from the UK), but every now and again it's good to splurge on a witty and fun gift idea!
