after i got home and checked my bag of fiber fill that i bought at walmart - it was a 1# bag - so, i've used approx. one and 1/3 bags. the biscuits i have now just cover the top of my standard size bed. i'm going to make flaps (for want of a better word) like approx 8" border all around and call it quits. i'm going to use hi-loft batting and maybe do some fmq on it b/4 i attach it.
