My mother-in-law took Ian shopping for a necktie but they weren't able to find anything in the wedding colors. So I decided to get a little ambitious and make one. After what seemed like forever at Joann looking at fabric, Ian and I decided on a dark brown with some pink and fuschia circles -- just right for the wedding without overwhelming the bridal ensemble with too much more pink (the flowers, bridesmaid dresses, and the groomsmen's ties are fuschia).
I made the tie using the Purl Bee's tutorial, which was really easy to follow. Believe you me I am not an expert sew-er but I managed to hand-sew the tie in a day. I believe the tutorial is for a boy younger than Ian (who is almost 10), but I think it's just long enough. If you're thinking about using the tutorial I wouldn't make it for a boy taller than 4'8" without making adjustments to the pattern.
And I managed to figure out how to tie a tie (this tutorial helped); at least now I know I can tie a basic four-in-the-hand tie if called to do so.
[I'll post pictures of Ian wearing the tie after the wedding.]
