Ombré HST Quilt Pattern

Inspired by a quilt that my friend Mary shared with me from Pinterest, I decided to design an Ombré HST quilt mathematically. This was the result.

I chose to use a gradient of eight different values, numbered 1-8 from lightest to darkest. I began by drawing a 7 by 9 rectangle in my graph notebook and randomly adding diagonal lines in each square. 63 squares meant 126 triangles, so dividing that by 8 different values, there should be 15.75 triangles of each value. I used six of my values 16 times each, and two of them 15 times each, filling in the triangles somewhat randomly while using the lower numbers more frequently at the top of the quilt and the higher numbers more frequently at the bottom of the quilt. The last numbers I filled in were 4 and 5.

Knowing that it would be easiest to make HSTs two at a time, I counted up my pairings and found that seventeen combinations were used an odd number of times (meaning that two at a time HSTs would not be very efficient). Seventeen was the perfect number of squares to add one extra row and one extra column to my design, so my design became 10 rows of 8 HSTs. My final adjustment was to make sure that I had used each value an equal number of times. Then I converted my numbers to the graphic above.

Make Your Own Quilt

This design can be made by choosing eight solids (or blenders or prints if you wish) in a variety of values. Tip: Use the black and white option on your camera phone to view the values of your fabrics; this way you can ensure contrast and verify that you have a range of values. Cut out ten squares of each of the eight fabrics. Choose your finished size of HSTs and cut the squares one inch larger. Create two at a time HSTs and trim to 1/2" larger than your finished size. Want a baby quilt? Use a fat quarter of each fabric. Cut 5" squares and trim HSTs to 4 1/2" for a 32" x 40" finished quilt. Want a throw quilt? Use a half yard of each fabric. Cut 8" squares and trim HSTs to 7 1/2" for a 56" x 70" finished quilt. Use the list below for cutting and piecing and the diagram that follows for block placement to create your version of my design. Or go random and use your design wall to audition the layout of your design. Have fun!

Label swatches of your fabrics #1-8, in order by value, lightest to darkest. Cut ten squares from each of your eight fabrics. Make the following 80 HSTs.

using 1 square of each value, create 2 HSTs (24 total from this section)
1-5 (example, use one value 1 square and one value 5 square to make 2 HSTs)

using 2 squares of each value, create 4 HSTs (32 total from this section)
1-2 (example, use two value 1 squares and two value 2 square to make 4 HSTs)

using 3 squares of each value, create 6 HSTs (24 total from this section)
1-4 (example, use three value 1 squares and three value 4 squares to make 6 HSTs)

Like it in grey? Try these Kona solids: (1) Silver, (2) Ash, (3) Iron, (4) Pewter, (5) Steel, (6) Coal, (7) Charcoal, (8) Black.

    What a great tutorial! I will definitely be using it and have already ordered my fabric. I plan to get my fabric cut in March and the quilt top sewn together in April. Thanks for all the work you put into writing this tutorial. Take care, Mary.

      Thanks, Yvonne. Anything I can make into a number game is a win for me. I used algebra for a recent quilt to maximize background area using the limited amount of fabric I had available. ;-)

      Thank you, Anja. I think the design wall is wonderful for throwing blocks up to create a random design, but you can just end up tweaking a design forever. I think it would be fun to play with computer generated numbers for true randomness.

      Thank you, Gerre. I had a great time at the meeting and I'm excited about everything the guild is doing. I look forward to seeing your Ombré HST quilt! :-)

  3. This is great Sarah , it really removes the element of chance from just mixing up the colours . Great tip too to use the camera like that

    This is just what I have been looking for! Thank you so much. What size was your finished quilt? I would like to make a twin size quilt but wasn't quite sure of sizing compared to yours. Thanks again!

      Hi Emma. You're welcome! I included measurements for a baby or a throw. For a 68" x 85" twin you could cut 9 1/2" squares to begin with and trim your HSTs to 9" for 8 1/2" finished squares. Another option would be to go a bit bigger for more length and then leave off one column so it doesn't get too wide. (Maybe use those HSTs for a pillow, or on the back of the quilt). I'd love to see what you decide on. Please share pictures of your project! And let me know if you have more questions.
