Do you have a little square of fabric?
 

Or two or more? Much more?

...and when you've got many of this:

... you can sew it together:
Face to face, but look carefully: Not the same colors on each other:

Do you want more? okay: More!

... and when you've got even more, you can make a quilt:

What a cute idea and presentation! Thanks.
