I've got a new DIY bow tie sewing pattern in the shop, that shows you how to make a skinny bow tie with a vintage style clip in the back. There's two different variations included in the patter: one for women when a long hanging tie, and one for men without the hanging tie. They are pretty quick and easy to make, with only a tiny amount of fabric, which makes them pretty addictive.
The pattern is based on the really cute vintage bowties that are super skinny and minimal. They sew up well with either a silky style fabric or nice cotton. I also like perusing the thrift store for shirts/pants/dresses made out of interesting fabrics that I can repurpose, since so little fabric is needed. They have been a good way to use up old fabric remnants I have laying around my craft room too.
The pattern is written for all skill levels, and covers all of the basics, like how to add a buttonhole. Also, I did some research on where to buy the bowtie clips and found that you can pick up a dozen of them for pretty cheap over at B. Black and Sons.
