Easy 25-patch block

My first project for 2015 is going to be this 25-patch block quilt. I'm making it 9x10 so it'll fit my king bed.

You start with strips that are 2-1/2" wide. A jelly roll is perfect.  Pair a light and dark (anything with some contrast works) right sides together. I cut 2 strip sets that are 16-1/2" long; I also cut one 2-1/2" square from the dark.

With right aides together sew each of these pairs together. Then sew these two sets together, alternating light/dark. You will have one strip set with 4 strips

Press to the dark strips:

Your strip set should measure 8-1/2"

You will now sub-cut this set into 2-1/2" strips. You'll cut 6 of them:

Rearrange alternating the light / dark in the left corner. You're going to sew 5 of these together 

Sew the extra 2-1/2" dark square to the end of the 6th strip set.

You can now sew the 6th strip set to the others already sewn together making sure your order is light-dark throughout.

If you are careful, you can nest the seams. 

Your block should measure 10-1/2" unf 

Note the placement of the dark/light squares.

I'll post the picture of the finished product in the next two days, after I get back to California   

Happy New Year!! Here's to a very healthy and productive 2015!
