If you would like to keep your directional fabric in the same orientation when you are piecing with half-square triangles (HSTs), this is a quick reference you can use for determining how to sew your two-at-a-time HST blocks. Note that this is not a detailed two-at-a-time HST tutorial but a supplements for creating HSTs using that method when working with directional prints.
Determine the direction you want your directional prints to run. This is likely going to be based on how the width of fabric (WOF) cuts of your fabrics are oriented.
Top: Robert Kaufman Fabrics / Carolyn Friedlander, Botanics, Hand Drawn Stripes in Fern – the directional print runs horizontally across WOF.
Bottom: Free Spirit Fabrics / Joel Dewberry, True Colors, Woodgrain in Teal – the directional print runs vertically across WOF.
Place the first square face up with the directional fabric in the WOF orientation.
If the second print is a directional print that runs vertically, place it (right sides together) on top of the first square with the direction running horizontally. Mark a line from the upper left to the lower right corners.*
If the second print is a directional print that runs horizontally, place it (right sides together) on top of the first square with the direction running vertically. Mark a line from the upper left to the lower right corners.*
*Note – if your piecing requires that the HST seam run from the lower left to the upper right corner, you would mark from the lower left to the upper right instead. The direction you mark the diagonal line will se the direction of your HST seam.
Follow remaining two-at-a-time HST piecing instructions.
