Hello everyone! I'm a newbie here, so please bear with my questions! My family and I are planning to attend an event over the summer for which we were hoping to wear some items I am sewing up; hopefully 2 kilts and three tartan-flaired dresses. As the event is outdoors and during the scorching summer of the Midwest USA, I was ideally looking for a tartan that was rayon(poly-viscose)/acrylic or cotton rather than wool, if only to save us from heat exhaustion. We were most interested in finding the Irish National tartan.

It's been days of searching, and unfortunately I cannot find any non-wool bolts or by the yard fabrics--and all of those are a little out of my price range! I'm appealing to your vast collective knowledge at large, then--does anyone know of anywhere I can find non-wool tartans that are relatively inexpensive and might have the Irish National tartan in stock?

Thank you in advance for reading!
