Hello VolcanicMink,

Hard to explain without a reference.. Your lacing should be a round_quite round part.

So, select a edge going all along your lace and in uvs/mat, mark as seam.

Do the same for the round edge at the end.

Your seams should do like the edges of a roll of paper.

Select all faces and unwrap using lscm.

You sould now obtain your uvmap. As it should have curves, you can try to get it more straighten with pining one vertice at one end and use "live uv unwrapping".

Hope it helps
