A while back I found a great pattern for a baby boy's skinny tie. I made a bunch for Bradley and have loved them. Now he is about growing out of them, so I'll need to tweak the pattern to make it a little bigger and a little longer. It's been so fun putting on these adorable little ties on him for church.
You can find the pattern that I used here (scroll through the options until you see a graphic with a pink tie on the left and a multi-colored tie on the right) in PDF format. The pattern that they have is good through about 18 mos.
