Thinking about diving in, looking at some wool and challis. Some of the donegals that he has posted are nice (on the site and similar pieces at Exquisite Trimmings). At 9cm, I found the knots too big for me. For those who have ordered wool ties where the fabric is a bit thicker, how have the knots been and have you been able to make modifications to taper them a bit? Can they make adjustments easily by discussing over email (e.g. sample photos from buyer)? Also, I'm assuming with Fedex, one often gets hit with duties? If so, what does that usually add to the price? Cheers.
