a quick frill question

hi, everyone!

as i was knitting along on the frill of my butterfly, i measured it (unstretched) and estimated that i'd need ~34 repeats of the frill pattern overall / ~17 per side. however, i've been looking at pictures / notes of butterflies on people's blogs and i'm only seeing 10-12 repeats per side. i want to do a size small. i've also read that ksh (which i'm using) stretches a whole lot when blocked.

basically, i'm wondering if i should i go for 12 repeats per side. that's The Plan at the moment. hehe...

thanks!
