A note to think about when designing your Tartan.

About the average Tartan Sett is somewhere around 6-8 inches.

This means that in 13 oz fabric, which has approx. 48 yarns per inch, your design needs to contain 312 yarns in one full repeat to yield a repeat of 6.5 inches.

16 oz. fabric has approx. 36 yarns per inch so a full repeat of 234 yarns will yield
a repeat of 6.5 inches.

Please remember that the yarns per inch figures I give here are examples only and will vary between mills. I took my figures from samples of Locharran Tartan that I have here in the shop.
