Mystery Quilt! Mystery Of Halloween: Clue 3


Making the X Blocks and Cutting Remaining Fabrics

Greetings Mystery Quilters!

It’s really spooktacular that we are already starting Clue #3. If you are joining us in the 5-Part Mystery of Halloween for the first time we hope you will stay awhile and start your mystery quilt project. It’s not too late to catch up!

The links below take you to the previous clues to get you started on my subtly spooky design.

Introduction to the Halloween Mystery and Materials List
Clue #1: Mysterious Block X
Clue #2: Tricks & Treats Strips and Triangles

I’m using two Northcott collections, Elegantly Frightful and ColorWorks Premium Solids, for my quilt, but you can choose your own fabrics. Visit our Facebook page #TQCMysteryQuilt to learn more about choosing the fabrics for this quilt, and to see what other mystery quilters have chosen for their projects.


Clue #3 is the quickest clue of all five. We are assembling the X Blocks, which I’m just batty about! Once your blocks are pieced and pressed, you may need to square them up. A 12”x12” square-up ruler is a great help. We are also cutting the remaining fabrics, getting ready for Clues #4 and #5. So make sure your rotary cutter and blades are in good shape. Do you need a new rotary cutter or ready for replacement blades? The Quilting Company has plenty in stock. I used contrasting thread in my photos so you can easily see the stitching, but you will want to go with coordinating or neutral thread for best results.

Ready for some bat-tastic fun? Let’s go!

Cutting (for Clues #4 and #5)

Dark print #1
24 squares 4 3/8” x 4 3/8” cut diagonally to yield 48 triangles (I)
Halloween novelty print
3 squares 19” x 19” cut diagonally twice to yield 12 triangles (J – 2 left over)
2 squares 10” x 10” cut diagonally to yield 4 triangles (K)
Bright solid
7 strips 2 1/2” x width of fabric (WOF) for binding
2 panels WOF x 60”

Making the X Blocks

Arrange 2 H squares (cut in Clue #1) and 1 each of Units 1 and 2 (made in Clue #1) as shown.


Sew 2 rows of 2 squares/units each.


Sew rows together to complete Block X, which should measure 12 1/2” square. Press seams as shown. Make 6.
