How to Make a Rubik's Cube Case

Measure a 3 1/4-inch square and cut it out of your black felt. Use the square as a template to cut four more squares. Measure a 3 3/4 x 3 1/2-inch rectangle and cut it from black felt. Set your black felt pieces aside.

Measure and cut a 3-inch square from one of your colors of felt. Use it as a template to cut a 3-inch square from each of the other colors. You should have one color each of red, yellow, green, blue, orange and white–the same colors used for each solved side of a Rubik's Cube.

Pin one color piece to each of the black squares, making sure the slightly smaller, color piece is centered within the black piece. Attach the remaining piece of colored felt to the rectangular piece of black felt. Pin the piece so it centered between the 3 1/4-inch sides and is over toward the right edge of the piece, leaving at least 1/2 inch black border on the left edge.

Thread your sewing machine with black thread. Put a layered square in the sewing machine and topstitch around the perimeter of the colored squares of felt. Repeat for each square and the rectangle.

Put a square back in the sewing machine with the colored square up. Move in an inch from the edge of a colored square and stitch a line straight down the square. Cut the thread. Move an inch over from the line you stitched and stitch a parallel line down the colored square. Cut the thread. Turn the square 90 degrees and stitch two more lines in the same manner. You should now have a grid of nine squares, just like the solved side of a Rubik's Cube. Do the same on each square and the rectangle.

Lay two of the appliqued squares' right sides together and sew down one side, using a 1/8-inch seam allowance. Set aside. Put the rectangle and another square right sides together, lining them up so the extra length of black border stick out on one side. Sew the two together down the opposite edge with a 1/8-inch seam allowance.

Open the rectangle and square and the pair of squares you just stitched. Lay the squares face down on the rectangle and square, lining up the edges so, again, the extra 1/2 inch of black border is visible on the left. Stitch down the right-hand edge, using a 1/4-inch seam allowance. Remove from the machine and open up the four-piece strip.

Lay one of your two remaining squares face down over the second square in the strip (on the end opposite the rectangle). Sew the square to the upper edge of the second square in the strip. Open the square, moving it out of the way and lay the remaining unsewn square, again, over the second square from the end of the strip and seam them along the bottom edge of the strip. Unfold to reveal a cross shape.

Cut a 1/4-inch by 1-inch strip of black felt from the remnants of your felt–preferably black. Fold the strip in half to create a 1/2-inch loop and pin to the right side of the square just below the rectangle in the strip. It can be on either edge, but the open ends of the loop need to line up with the edge of the square.

Fold, pin and sew one square at a time, around the second square from the end of the strip opposite the rectangle. The second square from the end will be the bottom of the cube, the four squares around it will be the walls of the cube and the rectangle will fold over to become the lid of the cube. The ends of the loop should be sewn into the seam on one face of the cube, up near the lid. Turn the cube right-side out and push out the corners.

Sew a 3-inch length of one half of the 1/2-inch hook-and-loop tape to the right side of the black border of the rectangle piece. Sew the other half of the tape inside the edge of the cube where it will meet the flap of the lid when it is folded over and tucked inside.

Open a carabiner clip and thread its end through the loop on the side seam of the cube.
