Mystery Quilt 2021 – Block 4

Updated: Jun 23, 2021

Welcome to our Mystery Quilt 2021! I hope you’re having lots of fun working on these Mystery blocks with us.

It’s time to get started on Block 4!

For Block 4, you will need: (choose the fabrics from “Perfect Union”) 2 blue fabrics 2 light fabrics

Block A Block B

We will be making 16 total Half-Square Triangles (HST) Block 4s: 8 of Block A and 8 of Block B


The cutting directions are as listed below: 8 – light HSTs cut from 4 squares 4-7/8″ (Color Option Block A) 8 – blue HSTs cut from 4 squares 4-7/8″ (Color Option Block A) 8 – light HSTs cut from 4 squares 4-7/8″ (Color Option Block B) 8 – blue HSTs cut from 4 squares 4-7/8″ (Color Option Block B)


Our fourth blocks will be positioned as shown above in our Mystery Quilt 2021! Notice the position of the blue fabric in the corners.


Please DO NOT start sewing blocks together at this time. We need to complete all blocks before sewing them into a quilt top. We are only laying them out on our design wall at this point.


The Rainbow Option:


For Block 4, you will need: (choose the fabrics from “Linen Texture” or your favorite collection) 1 blue fabric 1 red fabric 2 light fabrics
