Anything small from shushu the hair band to big as pillow covers!! Rectangular and straight shapes are easy. Luncheon mat?

But not to force yourself. I wanted to salvage nice pockets on the pants, so idea of making bag came up from there. 😊

Or another way is keep things until the needs come up. Like me, my son sometimes having cooking class at school and needs apron. And now I'm thinking to make it out of hubby's long sleeve shirt I was keeping for few years😂

And not to be a perfectionist from the beginning, it's ok. I didn't even used ruler on my bag project either😂

Good luck!!
