The darkness of the lines and the sail color varies widely between ships. The staining really increased the contrast of the stitching for the seams. The test sail came out a shade darker in the cloth and seams than the rest of the sails, because I didn't rinse the test sail off as vigorously. The seams are more subtle on the sails than on the test sail. The sails just finished drying and I'm looking them over. Reef bands need to be trimmed on the lateen, and main and fore courses. Lots of work left to be done.Are the thread lines supposed to be that dark? Just asking out of ignorance on my part. I’ve been debating the color of thread to use.
