I agree with those who said to not make it too detailed. The sewing on of buttons and the pencil cases sound good. Yo-yos in different sizes would be fun, especially if a few are put together to make a lapel pin or a large one for a pincushion. A square of fabric could be hemmed for a hankerchief, or a large square for a head scarf or neck scarf. An oblong of a heavier fabric like a heavy knit would make a neat dresser scarf. Something finished in a short time is far better than making a quilt block with no end in sight.
