SNAP! Snap tape - you have been dissed!
Not one single person spoke up strongly in favor of snap tape. Four people did suggest that, if I'm going to use snap tape, I should use a zipper foot. And a couple of those folks said not just any zipper foot - Linda, for example, recommended a Janome two-toed adjustable zipper foot.
But the vast majority of the commenters recommended using some kind of snap setter tool. Here are some of the links that people offered up to find snap setting tools:
What's funny, is that I use the low tech version of this approach (i.e., a hammer) to set in grommets on my chalk bags - but it never occurred to me that this would work for snaps too! Doh!
And two last cool ideas:
Shelia pointed us to this tutorial on making your own snap tape using twill tape and Mary said, forget the snap tape and baby clothes - a great home-sewn gift for new moms is a flannel sheet set (flat & fitted).
Oh, yeah - when I was googling snap tape to learn more about it, I found this nice overview about snaps on the Denver Fabrics website.
Thanks again to everyone for taking the time to leave a comment! I might just have to add a snap setter tool to my Christmas wish list... ;)
