Still More Red Blocks

Ten down - two more to go.  I have spent most of the day putting these two together and have been fighting with my wonder under.  I must be doing something wrong - but am having a hard time getting the backing off the pieces.  Maybe I am not ironing it long enough.  I have had to use a pin to get it started and that is so frustrating.  It is actually some softer than Heat and Bond Lite but it is certainly taking much longer when you have such a time getting the backing off.  I have some Steam A Seam 2 Lite which is really nice but expensive.  However I'll use those Joann coupons for that. 

I have laid these out on some red fabric that I have lots of and have quickly cut some squares to see how I would like sashing like that with a solid red border.  This is not the finished sashing - just a test sample.   I don't have enough of the background fabric to do much of anything.  Kind of like the look of this and, if I go this route, I will applique the squares on the sashing instead of piecing them.   Will use something other than the wonder under for that!  If you know a secret about easy peeling of the backing, please let me know!   (Click to enlarge)
