Make crumb blocks.

My granddaughter made her first quilt with b/w and assorted brights. I think the pattern might be called A Square in a Square. [ATTACH=CONFIG]576924[/ATTACH]

Zentangle quilt?

some great ideas, and some beautiful examples of B&W quilts. thanks for sharing

I made one for our bed, double slice from Jenny at MSQC. With the scraps I have made 8 quilts to donate for kids.

I used various black and white with red.

I love black and white with brights. Irishrose2 your square in square is beautiful! I love square in square patterns. You could also alternate the blocks switching the position of black & white and the bright.

A simple rail fence with alternate blocks turned 90 degrees, so you make a chevron pattern diagonally across the quilt would be fun too. You could toss in a row or two of brights in the 'rails' to make it pop! Like this one on pinterest: https://www.pinterest.com/pin/130674826657888649/

This came from The Big Book of Scrap Quilts and was quite easy:

One of my friends did a scrappy that I'm contemplating for myself. She worked with foundation such as a dryer sheet, put an odd shaped piece in the middle and then worked her way out with various shapes. No plan, just sew. Once the sheet was full, square it up and there's one block. Repeat.

I have done a rail fence with black and white but that takes more fabric and not really one to use up a variety of leftovers.
