And to anyone who does any kind of craft, the word 'futzy' means time consuming, detailed, and all around pain in the well-padded posterior.
This isn't to say that I'm not making progress. (Yes, this is the new purple dress. The sewing machine was threaded for it.)

The blogger
sugardale noted an article in Threads magazine regarding covering belt buckles. I was able to get that issue from the library and copy the information (purely for my own use, etc.) so I had it on hand when this time came around.
Um, yeah. The instructions are great. The execution is annoying. But on the second try I got it done and looking sweet.
Discourse follows. You've been warned.
The first time I was rushed and of course that's never going to make for a good result. The second time around I took my time and trimmed the fabric better. It probably didn't help that I was covering a buckle with curves. Or maybe it did. But when it was covered it did look darn sweet.
Note - if you do get that issue of Threads one thing I recommend is hand-sewing the first part. I tried it on the machine and while I like to think I'm pretty good at sewing I wasn't able to match the curve in any way. Hand sewing - perfect. Use a backstitch for strength.
I'm using regular elastic as my belt material. I wanted something soft that wouldn't show through the belt cover. That eliminated the BanRoll elastics since they have vertical ribs to make them, well, not roll. I went with regular elastic for the comfort factor and the note that it won't kink like the crisper materials will.
First time I threaded the elastic through the belt casing I didn't pay as much attention as I should and when the entire thing relaxed I was about 6 inches short on filler. ~sigh~ Pull that back out and try again. This time I left the elastic attached to the reel until I was done with covering and ironing.
I tried for a shaped end and that didn't go very well. I've got a mostly squared off end. Practice will help with that. Or all my belts have square ends.
The eyelets are all in place and the ones on the end of the belt still need to be tied off and clipped. The buckle end is complete, including the loop and the finish stitching.
I'm undecided about belt loops/thread loops on the dress itself. I can't do the basic loops on the side seams due to the invisible zipper so they would have to be offset. I think I'm going to wear the dress with the belt and see how it moves.
Finally, I did toss my pink dress in the washer. And it's 100% cotton all right. These will need to be ironed to look good after washing. But I knew that.
