I found a tartan (Irish County Tyrone - see below) that I both really like and is related to my family heritage but my prospective kilt maker says it only comes in "medium" (13-14 oz.) weight and I had hoped to have a kilt made of 16 oz. material. I have several lighter weight DIY kilts and one professionally made heavy weight (16 oz.) one which has the weight and "swish" I was hoping for in a new kilt. What differences would one experience between an 8 yd. kilt made of 13 oz. as compared to 16 oz. material? How much difference in expense (cost of material?) should one expect? What I really want is a County Tyrone in 16 oz. but alas...
