Locating eyelets at the right height on full length hose can be a tricky problem. Until the hose is suspended from the doublet it's difficult to correctly estimate how much the hose will stretch, so it's very easy to locate the eyelets far too high, a time consuming mistake to correct. To avoid this problem, make a strip of folded and reinforced fabric with holes for the points. This can use machine stitched eyelets, or a strip of leather between two layers of fabric and holes opened with a hole punch. Stitch this to the hose temporarily, much lower than you think you'll need it.
You can now lace the hose temporarily to the doublet, allowing you to mark where eyelets should be sewn in the hose.
