No Template Double Hourglass Block Tutorial

All seams are 1/4". Strips are cut along the width of fabric, approximately 42" wide. One strip set will make two Double Hourglass blocks.

CUT FABRIC: For each strip set, cut the following:

(1) 2.25" x 42" white strip
(1) 2.25" x 42" color strip

STEP 1: Place two strips right sides together, and sew along the long side. Press. I recommend pressing to the side instead of open for this block. It really helps your points line up.

STEP 2: Find the 45 degree line on your ruler. Place it along the bottom edge of your strip set. Look at the top of your strip set and make sure that the ruler is just past the selvage.

STEP 3: Holding your ruler firmly, make your first cut.

STEP 4: Line up the 45 degree line along the top of your strip set. Make sure it's nice and straight along the length. Line up the bottom of the strip set with the very edge of your ruler. This is the tip of your triangle so take your time to place your ruler just right.

STEP 5: Make your second cut.  Now you have a triangle!

STEP 6: Now line up the 45 degree line along the bottom of your strip set. The top of the strip set should just touch the edge of the ruler. This is the tip of your triangle. Cut carefully.

Continue down your strip set, repeating steps 3-5 until you have cut eight triangles.

STEP 7: Arrange in the layout shown. 

STEP 8: Pair up the triangles and sew them together using a 1/4" seam. 

STEP 9: Pin and sew together as shown.

STEP 10: Trim your block to 7" square.
