The first step would be to collect all your scrap pieces of fabric together in a pile.
For this crumb quilting tutorial, I used neutral tones and low volume fabrics for most of it and I had a separate pile of colorful and printed fabrics to add a pop of colour here and there as I went along.
I start with small square or thin rectangle-shaped scraps and find two of either width or length.
Each time I add a crumb to another piece I then press the seams with my iron to keep everything flat.
I start a section and grow it until I feel like I don’t have scraps that are long enough to add to it.
