2021 Modern HST BOM {January!}

The 2021 Modern HST BOM is finally here! (And goodbye 2020!) Get your rotary cutters and sewing machines ready...here is the January block!

There are a few new things with this year's BOM. We're exploring the modern characteristic of scale, and each quilt block will have one block made up of four smaller HSTs. For each quilt block, make your small HST 4 patch first. This finished size of your small HSTs will be half the finished size of your other HSTs. For example, my HST blocks are 4" finished (4-1/2" unfinished) so all of my small HSTs will be 2" finished (2-1/2" unfinished). To make the January block's small HST 4 patch, arrange your small HSTs as shown in the diagram below:

To assemble your January block, arrange your HSTs and the HST 4 patch as shown below.

In 2021, Zina and I are teaming up with Miriam of Quilt Africa Fabrics. Miriam generously provided me and Zina with some beautiful African fabrics for our 2021 quilts. She has also curated some beautiful color-coordinated mystery fat quarter bundles that are perfect for this year's BOM. They are available for purchase in her shop!

Zina is using some gorgeous red and yellow African fabrics paired with a black (and a hint of white!) background for her quilt blocks this year. 

After using monochromatic gray in 2020, I'm using ALL the colors in 2021! I haven't figured out exactly how I'm going to make all the prints and colors work together, but I'm pretty pleased with my January block. I finally decided on Kona Snow for the background because it really makes the colors pop.

If you are on Instagram, please share pictures of your completed blocks! Use the hashtag #modernhstbom2021 so we can find you. You can also tag me (@stephjacobsondesigns), Zina (@zanymouse) and Miriam (@quiltafricafabrics). If you're on Facebook, you can post pictures of your blocks on my Facebook page.


  1. Hello how much fabric will you need to complete the entire blocks

  2. How do I determine the size of the pieces to cut?
    I would like a finished size of approximately 4 inches. But how do I determine the size of the large and small triangles?
