okay, i decided i'm *finally* going to post a tutorial- esque thingy. so sorry it took so long, and i really hope people are still interested! its really not that complicated anyways. also, sorry about my crappy pics, it was the best i could do lol!
you will need: 2 rectangular pieces of fabric in the dimensions you want your bag, one large rectangle (roughly 3 times the width of the purse and half the height, its better to have more than not enough!) , fabric for the straps, and lining fabric (same dimensions as the body of the purse). the last label says lining.
sew the body pieces together on 3 sides (the longest sides were vertical on mine, but you can make it however). make sure the good sides face inwards when you sew!
now for the pleats. there are a million pleated skirt tutorials on craftster, so i'm just gonna summarize. hem the bottom of your strip of long fabric first. then, lay it out, fold , iron and pin you pleats in place (you might want to measure, or you can just eyeball it). then sew them together on the sewing machine. sorry if you're still confused, i don't know how to explain pleats properly lol.
okay, this is the tricky part! place your bag with the right sides facing outwards. now, place the pleats with the the wrong side up, with the "bottom" of the pleats towards the *top* of the bag and pin the pleats in place all the way around. sure the pleats are low enough to cover the bottom of the bag when flipped right side around. sew the pleats to the bag, but be careful not to sew the bag together! i don't know how ghetto your sewing machines were, but it was quite a struggle for me!
okay, hard part over, now for the lining. just like you did for the lining, put the good sides together and sew around the 3 sides. place this inside the bag.
To attach the lining, fold the hem of both the outside and the lining fabric towards each other. (i tried to illustrate this with a side view). then, sew over the fold (you might wanna sew straighter than i can draw!)
after this you're basically done! add your zipper or velcro and handles the way you normally do (you may do this before you line it). sorry if its confusing, this is my first tute! feel free to ask for any further explanation!
