Mystery Quilt! Mystery Of Halloween: Clue 1


Mystery Quilt Clue #1: Making the Block X Units

Kathryn Patterson, Mystery Quilt Designer

Welcome to The Mystery of Halloween, a free mystery quilt pattern brought to you by The Quilting Company and Northcott. This subtly spooky design will delight kids of all ages and backgrounds. There are no ghosts, witches, or other “supernatural” motifs – everything is nature-based and just creepy-crawly enough to create (and cuddle) a few goosebumps.

If you haven’t already done so, please refer to the Materials list in the launch post and get your fabric selections together. You will also need twin size batting for this 51” x 68” lap quilt.

This design requires only basic cutting, sewing, and pressing tools; if you are a complete beginner, I can recommend the Quilting Essentials tool pack from The Quilting Company. 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 mysterious fun? Let’s go!

About this Quilt

This fun quilt design is a great way to showcase Halloween fabric collections or even solids and prints from your stash. I used Northcott fabrics, including prints from the Elegantly Frightful collection and some coordinating ColorWorks solids.

Making the Flying Geese Units

Draw a diagonal line on the wrong side of each dark print #2 and bright solid A.


Place a marked dark square on each bright solid B, right sides together, raw edges aligned, and orienting line as shown. Repeat with marked bright solid As on dark print Bs.


Stitch just a thread or two to the outer corner side of each line.


Press each square open as shown, aligning raw edges.





Trim excess fabric from underlying layers, leaving approximately 1/4” seam allowance.


Now repeat the process to add another matching A square to each unit.


Make 6 each Flying Geese 1 and Flying Geese 2.


Making Unit 1

Sew a dark print #2 C to the dark edge of each Flying Geese 1.



Stitch bright solid D triangles to each side of each pieced strip.


Trim the dark print strips even with the bright solid triangles.


Sew a bright solid E triangle to each pieced triangle to make Unit 1, which should measure 6 1/2” square. Make 6.



Making Unit 2

Sew a dark print #2 F and a bright solid F to each Flying Geese 2.


Finger-press the pieced strips and each dark print #2 G triangle in half.


Sew a G triangle to each side of each pieced strip, matching folds.


Trim the F strips even with the G triangles to complete Unit 2. Make 6.

    I would like to download these patterns since I don’t have time right now to make this quilt. I was hoping there would be a way to save these clues and not to print them by using a massive amount of paper. Thanks for any information.

    Is it possible to have a printer friendly version? My laptop bogs down trying to generate 31 pages to preview. Thanks.
