About the Prism Wing Triangle Shawl
Prism is the easiest pattern in the collection and the most color-driven. Each half grows around a moving center increase, producing an angular wing shape. Make the second half the same way, then join the two short sides to create the center spine of the shawl.

Continue to size
The first 6 rows of the stripe pattern are complete. Keeping the 24-row stripe sequence, repeat Rows 5 and 6 until the shorter side measures about 22 in / 56 cm, ending with 2 rows of Color A. Fasten off.
COLOR HANDLING
Do not break Color A. Carry A neatly up the side while it is not in use. When changing color, work to the last 2 loops on the hook and draw the new color through those loops.
CENTER MARKER
Move the marker to the new center stitch every row. Missing that center increase changes the wing angle.
Join the two wings
Make two matching halves and join the short sides to form the center spine.
Make the second half exactly like the first. The RS of the first half becomes the WS of the second half once joined. Place the two short sides together and sew them to form the center spine.
Long-edge finishing
Join Color A with a slip stitch to the right corner. Ch 1. Work scbl through both thicknesses across the long side of the shawl. Fasten off.
BEFORE EDGING
Lay the joined shawl flat. If the center seam twists, correct it before adding the long-edge row.
Choosing colors
The easiest way to keep the striping cohesive is to let Color A act as the recurring anchor while B, C and D provide contrast. Four bright shades can make the shawl playful; a neutral A with three jewel tones produces a more polished result.
Troubleshooting
The center drifts: The marker likely moved to the wrong stitch. Each row’s center increase must be worked in the new center stitch of the previous 3-sc group.
The carried edge looks messy: Carry Color A consistently and keep the carried strand relaxed rather than pulling it tight.
The two wings do not match: Compare the short-side measurement and stripe count before joining. Correct any difference before seaming.
The shawl is too small: Your gauge may be tighter or the yarn thinner. Continue the Rows 5–6 repeat until the short side reaches the target measurement.
FAQ
Is Prism Wing suitable for beginners?
Yes. It is the easiest of the three Moth & Wing Shawls patterns. The main challenge is remembering to move the center marker every row.
Can I use fewer than four colors?
Yes. You can simplify the stripe plan, but keep track of your own sequence so the second wing matches the first.
Why is Color A not cut?
Color A returns frequently in the 24-row stripe repeat, so carrying it neatly up the side saves ends and keeps the sequence efficient.
Do I need to block it?
Blocking is recommended to straighten the center seam and shape the long points evenly.
