Hi All, I am new to using natural rush and grossly underestimated how much I would need to weave a small bench/cat bed I built. I am about halfway through and am out of cattails. I am thinking of just buying some pre-twisted natural rush and continuing on but am wondering if there is anything wrong with that approach other than mismatching rush. My cat is probably going to rip a hole in this immediately anyway so that may be the least of my concerns...
