Pinwheels I have used up a lot of 4 and 5 inch scraps this way-and every one seems to love them. GDs all wanted their quilts with all the triangles

I agree with the pinwheels. Missouri Star has a great tutorial...you put 2 squares facing together and sew all around the outer edge, cut from corner to corner turn and cut corner to corner again gives you 4 pieces. Iron open and arrange in pinwheel fashion. Cute, quick and easy!

I have added a "background" triangle to each side of a square and that kind of frames them and puts the inside square on point. You could also choose a material you really like and cut squares of that color and alternate squares with your favorite material. Good Luck

My sister took a bunch of 4" squares and sewed them into a 44x72" top but instead of a quilt she made a beautiful lined jacket out of it.. She used white flannel for the lining and a simple Simplicity pattern. It is adorable ...I loved it! She wouldn't let me have it...had the nerve to tell me to make my own!

I picked up baggies of 4 inch squares in an antique mall and I made 4 patches from them, set them on the diagonal and bought a solid/tone on tone and use them with the 4 patches. Used the solid/tone on tone as borders. They came out beautiful. I made sure that the fabric squares in the 4 patches were all different.

Pinwheels!

Some mentioned the light and dark pattern. I have one and just love it. Simple and used so many odds and ends of squares. A joyful piece that was such a surprise for me. Give it a try.

I have done this a lot, once you have the half square triangle blocks you can use any log cabin layout.

Disappearing NINE block looks great and is fun! Enjoy !

You have so many options! I love the many variations of Disappearing 9 Patches as others have suggested. Jacob's Ladder is made with HSTs and squares.
You can cut some of the 4" squares into quarters and have some smaller 2" squares to work with. Scrappy Irish Chain is always an option if you have background fabric to add.
