Back to the Butterfly Wing

I'm still working on the other wing but it's been a month since I posted.  I wanted to pop in and say Hi.  I thought you'd like to see the wing I've finished with the two parts together.  I've put it on the black background fabric for the photo.  It gives you a better idea of where I'm headed with this.  I'm almost done with the other wing after a time consuming big mistake I made and had to take out.  I also spent a bit of time on a RR square this month between all the May birthdays around here.  I find I spend more time trying to come up with ideas than I actually spend stitching.

Butterfly Wing 11

Speaking of RR's, I read somewhere that when you do work on a square you should leave 1/2 " bead free along the edges that are going to be stitched to other squares or borders.  I've never done that and just use a zipper foot to stitch the fabrics together and think that a scant 1/8" is plenty of space to allow.  I think a 1/2" bead free area especially in a seam that goes out to the edge looks unfinished.  What do you do?  I guess you could enclose enough beads for the recipient to finish it off.
