I have, and sometimes I really enjoy just grabbing one and getting to cutting with no figuring. Half the time I don't even have a pattern so I'm figuring yardage along with everything else. So oftentimes actually using a pattern is a big treat for me.
I only buy kits when I can get a really good deal. Right now I have a 40% off one item coupon from my LQS - and I love using that to buy a kit. I hope to get there this weekend and will be looking to see what they have in stock.
