This is a golden yellow long sleeve skinny t-shirt with zipper teeth trimmed neckline that I sewed for my son, it was part of this look. And here's how I made it.
Supplies needed:
:: t-shirt pattern (I used Made By Rae's Flashback Skinny Tee)
:: long metal zipper
:: disappearing ink marker
:: diagonal cutter pliers
:: scissors
:: liquid seam sealant
Instructions:
Take your t-shirt pattern and instead of following the given neckline, just cut straight across, then cut out your t-shirt.
Measure the neckline. From that measurement figure out how long the zipper will need to be, making sure that you have enough zipper tape let on both sides to allow for seam allowances, as you don't want to be running your sewing machine over zipper teeth !
Take your metal zipper, unzip the zipper so that the zipper pull is next to the bottom stop, just above the zipper pull in between zipper teeth, cut all the way across, this will remove the zipper pull and separate the zipper teeth. With disappearing ink marker, mark the needed length, then also mark one seam allowance length away (towards the edge).
Remove the zipper teeth between the 2 marks by using a diagonal cutter pliers to cut them and or pull them off.
Using a scissors, cut off the excess zipper at the 2nd mark.
Apply a small amount of liquid seam sealant to the cut edges, this will prevent the fabric from fraying.
Pin the zippers onto the t-shirt neckline.
Using a zipper foot on the sewing machine, sew the zippers onto the neckline.
Following the t-shirt pattern sewing instructions, finish sewing the t-shirt together.
All done !
