Friday Night Sew In

So I thought these were every Friday night, but went to check into it and ....there's no party tonight.  Oh well, guess I'll have my own party!!

Here is my set up for the night.  I am ready to hit the ground running!  Chevrons and more chevrons ...

I got my spiffy little $6 mat today to trim up these 3 inchers without having to turn my larger mat.  And see the rotarty cutter?  Reularly $21.99 on sale for $6.99.  Yes!  I love a good sharp blade.  I was sawing fabric with my old rotary cutter dull blade and that wasn't fun!

I am trying to decide between a flannel backing (using these 2 above)

or Kona solids on the back using these 3 colors. 

What to do?!
