If it's 44" fabric, and you want 2 inches on all sides of the quilt top for quilting, you could do it like this:

Cut the yellow fabric down to 64", so you have a big 64" x 44" piece. Cut the 64" piece in half lengthwise so that you have two 64" by 22" pieces (the top and bottom yellow strip).

Cut the blue fabric down to 32", so you have a 32" x 44" piece. Cut that piece in half lengthwise so that you have two 32" x 22" pieces. Sew these together on the shorter seam to make one 64" x 22" piece.

The end sandwich would be:
Yellow: 64" x 22" piece
Blue/yellow: two 32" x 22" pieces sewn together, for a 64" x 22" piece
Yellow: 64" x 22" piece

You would have enough yellow left over to do a yellow strip between the two blue/yellow pieces, if you want (which would look sort of like a letter I), but you don't have enough blue/yellow to go all the way across without some kind of seam in the middle, I don't think.
