So, I decided to make my own - for a fraction of the price.
A purse - preferably one that is sturdy and has a large main compartment (as opposed to a purse that has a few dividers already built in)
Headliner fabric - thats the stuff you'd probably find on the roof of your car (inside, duh) but they sell it at any fabric store. I probably used about a 1/2 yard.
Forgive me in advance but I don't know the technical terms for any of this stuff. Also, I'm not much of an instructions gal so I pretty much just winged it. As with all DIY projects, you can find a zillion tutorials online if you want to attempt your own bag.
Here's the purse I started out with. I think it was about $15-20 at Marshalls. (I don't remember the exact amount but I try not to spend more than $20 on anything so I assume that's how much it cost.)
Next, I laid out a long piece of the headlining fabric, the same width of the pieces of cardboard I already cut out. I figured out where I wanted to secure a few pieces of velcro and then sewed it on. I forgot to take a picture of that step but here is a picture from later on in the process but it shows what kind of velcro I used:
Next, I folded the piece of fabric in half and then sewed seams in where the folds/bends in my camera bag insert would go. I hope this picture explains it because I don't know how I would with words.
In the picture above, I already sewed two straight lines where the insert would fold up along the sides of the purse. The opening that I am holding up will be at the bottom of the purse and won't show - so I wasn't worried about doing anything major to hold it together. To close up the ends, I just sewed a straight line down the two sides of the insert. Here it shows how it will look inside of the purse:
Disregard the horrible sewing job but James was napping and I knew I probably only had another 10 minutes to finish this project. Yes, I was rushing. No biggie though - all of this would be inside of the purse and not-so-visible. See...no more wiggly lines!
I've seen several tutorials online that make sides for the insert but that would have been too fancy for me. Instead, I just made three dividers to slip inside. Because they have velcro on the ends, they can be adjusted to fit whatever it is they are dividing:
With these all sewed up and inserted into the insert, it looks like this:
I could make additional dividers if I wanted to tote around additional lens or other items. For now, it holds a spare lens, my camera (old camera is in the pic above for staging purposes along with some rolled up batting in the 3rd compartment) as well as a wallet, phone, etc. can all fit!
Much better than what I used to have to carry around in addition to my regular purse!
