Sort them into pairs. Do half-square triangles. then sash each square with a 1 " strip on all four sides. Throw them into a bag. Pull out two. sew together. pull out two more sew together. Do that until you have them all sewn into pairs. Then repeat the process until you have them all sewn into fours. Rotate the triangles if needed to keep the same prints from adjoining. Then sew two sets of four together. Sew another two sets of four together. Sew these two four-sets together. Then sew a single set of four to one side. Repeat these steps until you have used all the half-square triangle blocks. Add a 4" black border around and you have a great quilt!
You might even add solid inner borders of some of the colors that you really like to increase the size.
