Sail to leading edge tube? Ways and means? Please extend the following ways-and-means list to the best of your ability. Assume the sail is packed separately from frame members. Explore ways and means of making the sail and attaching it separately to the frame.
Tape edge of sail to LE; rotate LE; then cinch the LE tube to noseplate or keel and to spreader. Plan ahead for the sail material rolled up. Sacrificial tape per flight session.
Velcro hook on sail edge. Velcro loop on LE tube. Set the hook to loop. Roll LE. Set LE tube to keel/nose and to spreader. At packing: peel off the sail. No wasted taping here.
Bond keder rail to LE tube. Sew keder to sail. Pull keder cord into keder rail for assembly. Wrestle with the consequence of having such deal as this will affect happy packing.
Have small or large hem in sail. Slide sail onto LE tube. Consider stuffers, formers, ..., into the cavity.
Have Velcro hook line on sail; have loop strip on sail. Wrap sail over LE tube and cinch the Velcro parts.

Certainly! Here are some additional ways and means to consider for attaching a sail to the leading edge (LE) tube, assuming the sail is packed separately from frame members:
Snap Fasteners:
Install snap fasteners along the edge of the sail.
Attach corresponding snap components onto the LE tube.
Fasten the sail to the LE tube by snapping them together.
Zipper Closure:
Sew a zipper along the edge of the sail.
Affix the mating part of the zipper onto the LE tube.
Zip for assembly and unzip for packing.
Magnetic Closure:
Embed magnets into the sail edge.
Attach metal strips or magnetic components onto the LE tube.
Allow magnets to snap together for secure attachment.
Lacing or Grommets:
Incorporate grommets along the sail's edge.
Lace a cord through the grommets, securing the sail to the LE tube.
Adjust tension for a snug fit.
Bungee Cord System:
Stitch loops onto the sail's edge.
Stretch bungee cords from the sail loops to attachment points on the LE tube.
Adjust tension as needed.
Clips or Clamps:
Use clips or clamps to secure the sail to the LE tube.
Choose durable, lightweight options for easy packing and assembly.
Magnetic Strip and Metal Plates:
Attach a magnetic strip to the sail's edge.
Affix metal plates onto the LE tube.
Align the sail and LE tube, allowing the magnetism to hold them together.
Slide-in Sleeve Design:
Design the sail with a sleeve that slides over the LE tube.
Ensure a snug fit for stability during flight.
Combination of Methods:
Implement a combination of the above methods for added security.
For example, use Velcro in combination with snaps or lacing.
Inflatable Tube with Integrated Sail:
Explore the possibility of an inflatable leading edge tube.
Attach the sail directly to the inflatable structure for an all-in-one design.
Remember to consider factors such as weight, aerodynamics, ease of assembly, and durability when choosing the method that best fits your needs. Additionally, testing different approaches may help in determining the most efficient and reliable solution for your sail attachment.
Mods of some of the above:
Snap parts not on LE tube but on sail; snap parts all on the sail. This leaves packing frame segments in a happier deal.
Zipper parts not on LE tube but on sail; all zipper parts on the sail. This leaves packing frame segments in a happier deal.
Magnetic deal: keep LE tube clean; put all the magnetic deal onto the sail; this leaves packing of frame segments in a happier way.
Have LE tube be a keder rail itself. The sew keder to edge of sail. Slide keder cord into the keder rail.
If LE is made of two running tubes, then consider pinching a keder and then using ties to hold the two tubes together.
Sock deal: if HG is full DS, then a sock deal might be a way.
Other methods are invited from anyone.
