I just started sewing hexies last night! I'm trying to use up scraps so whatever it is I'm making will be all from scraps.
It's been a LONG time since I've done any significant amount of hand-sewing - I don't even hand sew binding. I was getting flashbacks to being a kid and stitching up felt mice for our cats to play with.
I made my hexies out of cardstock and a punch, so I have about 300 of them. I plan on leaving them inside the fabric until the last possible moment.
I worked on it for forever last night (punching all the pieces) and sewed all of 8 hexies.
I also learned first-hand why hand quilters don't like batiks. I have a TON of batik scraps, but after just one hexie I've decided I don't hate "future me" enough to commit her to having to sew together a bunch of batik hexies. So there will be just one batik hex in my quilt...it's a good thing I like scrappy quilts! If I stick with it long enough to make enough for a quilt, that is...I might end up with a throw pillow instead, LOL.
