I have a number of kilts from Scotweb. 5 yard as well as 7, and 8 yard. ALL great kilts. When I first started killing (12 years ago) my research showed that MOST (all) kilt makers in the UK use fabrics from a fairly small number of Mills.

I have a great respect for USA kilts, but haven't purchased any kilts from them.

With 14 wool kilts in my closet, AND knowing that most kilt makers buy fabric from the same mills, between the two you've listed, I'm in favor of pricing, and Scotweb.
