Quilted Xmas Tree Ornament - the next steps

I'm still working on the pink & green Christmas ornaments. Last night I paper-pieced the side sash pieces, because I really didn't want to deal with 1/4" square cornerstones by themselves. Here you can see the two rows of blocks next to the pre-made sashing.

This sashing was really easy to make by paper piecing because I just measured it out on graph paper and luckily all the seams fell on grid lines. You can see I labeled the paper "P" for pink and "G" for green. It's surprisingly easy to get messed up, even on a simple thing like this!

I may have gone over the legal limit for pins per inch here. It took 12 pins for less than 5 linear inches of seam - and I had to do it four times over.

It ended up being much more accurate than it would otherwise have been without the pins though.
Now I just have to figure out what to do next. Do I bead or do I make my tiny little quilt sandwich and quilt it, then bead it? Any hints? I'm afraid if I bead it first (and I plan on LOTS of beads) then I won't be able to quilt it without running into the beads, even with my 1/4" foot. It's a worry; I guess I'll sleep on it. 8-)
