I have the instruction for the squares for the size you need to cut. For the 1 1/2" x 3" you need to cut one larger square 6" and the small one cut 4 1/2" I keep my instructions wiht my rulers so I have them for reference. Have a great day, Huggies, Fay........Then you can look at the tute again for making the flying geese blocks and you can use the measurements I gave you. Good luck.
