I still have a couple of construction tweaks to do and I want to add a handle to make pulling it out of the cubbie easier and maybe a label pocket for the front, but I'm calling the first prototype for storage boxes for the IKEA Expedit shelves a success. And no spray adhesive necessary. Channeling my inner Peter from Male Pattern Boldness, this one is covered with old bedsheets as a "muslin."
It fits into the cubbie perfectly, which means my measurements and the pattern are good. Whew, pretty good for a first go at it. If the contrast at the top isn't wanted, assembly can be reversed so that the flap is on the inside and in a matching print so it blends to the lining.
But … each bin needs 2 yards of 44" fabric, which means if you have your heart set on a particular print and it's not on sale, there's really no savings over just buying something pre-made. Of course, if you do have your heart set on a particular print, you'd also never find it as a pre-made bin. And if you can shop the stash, they're free. Right? ;-) Looks like I'll need to shop the online sales or head to Joann's with coupons since the stash isn't holding a bunch of bin fabric at the moment.
You'd also have to figure in cardboard if you don't have any. But I saved all the boxes these shelves came in and that will be more than enough. (And since I won't have to put all of that into the trash/recycle bin, that's an added bonus.)
This bin can be completely dissembled, which means it can store flat and you can wash the covers if necessary. I don't know if those two qualities will mean anything to me, but since I'm thinking of making a downloadable pattern for these, I thought it might be a plus for someone else.
I think the whole thing, from cutting out fabric and cardboard to sewing seams and pressing seam allowances, took about an hour at the most. I was watching the tube as I was doing this (Deadliest Catch - RIP Phil Harris) so I'm being generous with the time estimate. The total time per box should go down if/when I'm in assembly-line mode because the cutting can be stacked when working on multiples.
