How to sew triangles

Cut a strip of fabric the width of the height of your triangles and cut it lengthwise along the line of each side of the border for the Trios Lap Quilt.

Step 2

Cut a 60-degree line along the top edge of a fabric strip with a ruler; the ruler’s cutting edge should be at an angle of 60 degrees to the fabric’s surface, and the seam should be the same width and depth as the previous section.

Step 4

Mark the width of the triangle on your fabric strip at intervals – for the Trios Lap Quilt, this is 4in – then move the other 60-degree line along the bottom edge of the fabric strip and line it up with the 4in mark on the strip.

Step 6

Make as many triangles as the fabric will allow by moving the ruler along a 60-degree line along the top edge of the fabric strip, this time lining it up with the 4in mark on the top of the strip. Sew them together using scant u00bcin seam allowance.
