The bob is a short, sassy cut that's been popular since the 1920s. It's low-maintenance but still manages to be totally fabulous. Celebrities from Keira Knightley and Aleksa Palladino to Katherine Heigl rock the bob on red carpets and in supermarkets. Getting the perfect bob with a weave requires the perfect sew-in technique.
Don't expect to get your bob with short extensions. You definitely want to go with longer extensions — even a foot long — so you can cut it to your perfect length. If you haven't sewn in a weave for a bob before, it's hard to tell whether you want one that's exactly chin-length and blunt, or one that's longer with a fringe. Make your bob your own. Some people like shorter backs and longer fronts; others like to razor cut the ends of their bobs to get texture.
Make sure you braid your natural hair into spiraled cornrows super-tight against your scalp. This will give you a better surface for your sew-in weave. You can use a weave cap or incorporate your natural hair into the weave, but it isn't the best choice with a bob. You need some height and fullness, and you're more likely to get it with a full weave without natural hair out. Make sure the cornrows are close to each other; the closer they are, the more volume you'll have.
Start at the lowest place on your scalp where you want to sew in a track. It should be at the very bottom of your cornrow. Use your curved weave needle and correct thread to attach it to the cornrows you created. It'll make a straight horizontal line from one side of your skull to the other. Once you've finished sewing it to the cornrows, create a knot to secure it. Then move on to the next one. Again, keep the weaves close to each other to make it look fuller and more natural. Keep sewing in your weaves until you get to the front of your hairline.
Create a part in your hair where you want it on a regular basis. This is especially important if you want bangs. Once you've finished, cut away the hair a bit at a time until you've achieved your bob. Try out a side part with an angled bang for a super cute look. You can even head into a salon with your completed weave and have a stylist help you create your bob.
