Modern HST BOM 2022...April Block

This post contains affiliate links. 

It's April 1 which means the release of the fourth block for the Modern HST BOM 2022. It seems like half rectangle triangles have been EVERYWHERE lately! (I think it's the first time I've been on trend with anything.) If you're a member of the Modern Quilt Guild, check out this Modern Fundamentals article by Sarah's all about HRTs.

For the April block, these are the block units you will need. Just three kinds of block units this month!

I designed the April block. One of the things I'm enjoying about designing this year's BOM is the different angles and shapes the addition of HRTs adds.

To assemble the March block, assemble your block units into rows as shown in this diagram. 

All of the blocks for the 2022 HST BOM will be 16 patches. (There aren't any bonus blocks this year, but I will be releasing some of the blocks we didn't choose for the BOM throughout the year. They're just too good not to use and will make some awesome quilts!) You can use any size block unit you like, and the half rectangle triangles will be a 1:2 ratio. I am using the AccuQuilt GO! Half Rectangle Triangle Die (3" x 6" Finished). My 16 patch blocks will be a whopping 24" x 24", and my completed quilt top will measure 72" x 96"! My squares and half square triangles will be 6-1/2" (6" finished), and my rectangles and half rectangle triangles will be 3-1/2" x 6-1/2" (3" x 6" finished).

Zina will be using the Deb Tucker Studio 180 Split Rect Ruler which is available from many online shops including Fat Quarter Shop. With this ruler, you can make multiple sizes of half retangle triangles in the 1:2 ratio needed for the BOM. Zina is also making 6" finished block units (24" finished monthly quilt block). We like big blocks!

The great thing is you don't need a fancy die cutter or ruler to make half rectangle triangles. When doing some research online, I stumbled across this AMAZING 2019 blog post series from Swim. Bike. Quilt. Everything you need about making half rectangle triangles can be found in these posts. If you're feeling apprehensive about making HRTs, please check it out!

I'm sure there will be some questions, so please feel free to ask in the comments. If you're on Facebook, you can check out my posts and join the discussions on my Facebook page.

Happy sewing!


  1. Very cool block! I see birds....


  2. Cool block, I could see making a quilt using just this block (I may actually do that). I will say that these half-rectangle triangles did throw me for a loop when I first tried to make them without any special rulers, just couldn't figure out how to trim it correctly. I did buy a different ruler, Deb Tucker's Split Rects, and was able to figure them out after a couple of tries. I'm still a bit behind on this years project, just have the first block done, but do have all my HST's stiched together and the other solid pieces cut! Hope to get caught up this month.
