When I was a kid my mom used to sew her bra herself. Later she sewed a few bra’s for me too….Later on I myself did some modifications over my mom’s bra’s.
Now I decided to learn more about bra construction and make the basic bra with crochet hook and yarn. I found a great pattern from Kusine.com!
Having crocheted the cups of my crochet bra, I started to construct my own bra band and straps based on reading various bra sewing tutorials. The best one I found was Lenna’s Sewing. Another excellent resource is The Pattern School.
