TAST 91 is the Straight Feather Stitch (worked from right to left). I tried it out with perle #5 (yellow), perle #8 (hot pink), perle # 12 (light blue), and accentuate (black).
TAST 92 is the Crossed Feather Stitch (worked from left to right). I did the first step in hot pink, with the second step in hot pink part of the row and light pink the rest. The second try, I used black accentuate for the first step and a black and gold accentuate for the second step.
TAST 93 is the Plaited Feather Stitch (worked from right to left). I tried light blue perle #12 with black perle #12; gold keinik #8 with black perle #12, and black perle 12 for both steps in the upper row. In the bottom row, I made a wider, shorter stitch. First I used black/gold accentuate with green accentuate, then black perle #12 with green accentuate.
