Ugly Christmas Sweaters – HST Bonus Sewing Machine Mat Tutorial

Posted on: April 29th, 2016 by Lorna McMahon
The instructions for all 21 of the blocks in the Ugly Christmas Sweaters QAL have been given. Today’s tutorial is for the Bonus 2.5″ half square triangles! If you have quilted along, and have made the 20 blocks for the Maxi size quilt, you will have 40 Bonus 2.5″ HST’s.

I chose to use my HST’s to make this beautiful 16″ x 25″ Sewing Machine Mat. That way I will always have a reminder of the Ugly Christmas Sweaters quilt, how much I enjoyed making it, and how much fun it was to have you all quilting along with me!

This 16″ x 25″ Sewing Machine Mat was made using 40 pieces of 2.5″ squares. I used my Bonus HST’s, but any 2.5″ squares will work to follow this tutorial.

Here are the requirements:
40 – 2.5″ squares
32 – 1.5″ x 2.5″ strips
9  – 1.5″ x 14.5″ strips
2  – 1.5″ x 25.5″ strips
2 – 2.25″ x 42″ strips of Binding
Batting and Backing to cover 20″ x 30″

Step 1:  Arrange your 2.5″ squares into a grid with 8 pieces per row and using 5 rows.

Step 2:  Sew the 1.5″ x 2.5″ strips to the bottoms of the pieces in the first 4 rows.

Step 3:  Sew the pieces into columns.

Step 4:  Sew the 1.5″ x 14.5″ strips between each of the columns.

Step 5:  Sew the 1.5″ x 25.5″ strips along the top and bottom.

Step 6:  Layer the backing, batting and finished top. And baste.

Step 7:  Quilt the layers. And then the trim edges.

Step 8:  Apply the binding.

Step 8:  And ENJOY!

    So beautiful, thank you for the tutorial! I see that you are using your walking foot for the quilting. I have been having trouble with the walking foot, when I use it my stitches are very uneven, I live in Athens Greece and there is no Bernina representative here and I can't find the solution!Myrto
