ANGLED WING II - SEWING DETAILS

SPREADER SLEEVE OPTIONS
To make sleeves for the spreaders, #5 & #6, near the ends of both wings, you could either:
A) Sew panels in place over Panel B.
or
B) Use the natural fold created when joining separate pieces of fabric together when using a folded butt joint seam.
SEWN PANELS
Step #1: Add reenforcement patches. Spray mount material to hold in place or use adhesive backed fabric & then sew in place.
Step #2: Sew in place ripstop loops.
Step #3: Cut sleeve panels, fold top/ bottom for hemming & sew these edges,
Step #4: Fold sides and hold in position with spray mount.
Step #5: Position on Panel B and finish with straight & zig zag stitches.

FOLDED FABRIC JOINT
Probably would use this type joint seam either because a joint is needed anyway with the fabric width used or you are using diofferent fabric pieces for the graphics.

Step #1: Cut wing panels with 1 1/2" extra fabric on each side.
Step #2: Hold adjacent panel pieces together as shown and straight stitch together.
Step #3: Trim 1/4" off end to provide straight and uniform pieces.
Step #4: Fold over each end of the sleeve at an angle and sew in place. This creates a hem at the ends of the sleeve.
Step #5: Sew in place reenforcement pieces and ripstop loops.
Step #6: Fold over the top 1/4" and fold the entire sleeve flat.
Step #7: Pulling each side flat, stitch & then zig zag stitch to finish.

The above steps "read" complicated, but after the first time or two, it is done a second nature.
