Super easy and fast, you can whip up a ton of these in one afternoon. I got my shirts from the Goodwill Outlet store for $1.59/pound and had my husband sort through his ties.
1 man's long sleeve dress shirt
Step 1: Getting Started
Cut the sleeve so you have about 13.5 inches
Sew up the bottom and miter the corners if you wish to give it a flatter bottom.
Step 2: Making the Tie
I cut the tie to a length of 21.5 inches tip to tip.
Zigzag stitch the raw end and you're done!
