I was using a zig zag (the 3 point one) and I went ahead and ripped out the stitches and just tacked it down on either end and made a casing, sort of. I'm not doing blind elastic though, I'm turning and topstitching with a cased elastic.
Well, I know you already said you were.. but, you would, of course, stretch out your elastic quite a bit while sewing it down, and being mindful of not stretching your fabric with it. Oh.. I'll back up just a bit and make sure you're using quality elastic as well... because you don't want to go to all that work for crapp elastic that will break right away. I like to use the stretch-rite brand of polybraid elastic.. I prefer to use the 1/4" on most things, but I know some mamas like 3/8" on mediums and larges because it does have a bit more 'pull' and sturdiness to it. Otherwise, if you want the clear stuff, make sure it really is Lastin brand elastic. There are other clear elastics, but this is really the best stuff.
On to sewing again...
If your zig-zags are too narrow, then there isn't much recovery that can be made after you 'let the elastic go' when you're done stretching/sewing. I set the distance/length of stitches to probably a 3 or so? Maybe 2.5? (and yeah, it all depends on your machine! I have a gorgeous Bernina 1010.. a beauty of a used, sturdy machine!).
Hope that helps... (if not, I'll try to word it better
