Another one:
First the plans:
The smallest diagram is a layout of pentagons relative to triangles.
The biggest one indicates a route from one end (pentagon 1) to the other (pentagon 5), in red, and the beginning of a mirror of it in orange.
The medium one shows all five loops from pentagon 1 to pentagon 5 and back.
Then some steps:
Paper triangles (patterned and blue, back to back), embedded in tape, and held together with monofilament.
Following the plan, each pair of paper triangles was taped to the string, with care taken as to which side of the line it should be on, if the patterned side were face up. They are labeled with which pentagon they are part of.
The bottle rings designate pentagon five, the top of the model.
There is one extra triangle labeled five, due to a mistake. It was removed and repurposed as the model was completed.
Starting with each of the triangles marked '1', start to match the nearby triangles with matching numbers. Wherever there's a figure 8 in the plans, cross over the monofilament. Temporarily tape the triangles together. Add unlinked triangles where appropriate (there are ten triangles with no monofilament through them).
Not pictured: Keep following the crossovers and matching the pentagon numbers from the plans, as full pentagons are formed, remove the temporary tape, and tape them together permanently.
And the final product:
