Well, the first problem I ran into after cutting all the fabric and what not is learning the whole trick "right sides together". I make this mistake to this day and each time I scold myself. Each time, I find a new and interesting way to overlook it. This particular problem happened with the straps. As you can see from the picture below, the raw edge of these straps are supposed to go on the WRONG side of the purse, the side no one sees. You can also see why faded jersey cotton looks like crap next to this particular type of fabric.
Here is the same shot but with a white background for more contrast.
Well, let me some up what I learned with this purse:
1) How to box corners. On this particular purse, I went over board and now the purse sits wide open.
2) How to get strap edges to go in the wrong side of the purse
3) Do not buy fancy fabric and use it on a pattern you have never made before
4) Jersey cotton is the devil
5) Interfacing is awesome but requires patience.
Everyone I showed it to was very nice about it. They told me I did a pretty good job and the straps were hardly noticeable. They were impressed that it could stand up and that I edge stitched the sides. Looking at it now, maybe it isn't as awful as I remember it but the result was not what I had hoped for.
The good thing is I didn't let this deter me. I went on and found some actual patterns to buy. But that is a whole other can of worms...
