Xylie, That's a hard to read post. I hardly found your answer in with the quoted parts. Wonder why???
125 pounds at 5' 4" is for 25 year olds. If I remember correctly, you have past that. Try 100 + 5 pounds for each inch over 5 foot, then add 5 pounds for each decade past 25. You'll come out in the 140 range. Add a little for your body type and 150 sounds perfect.
For me, 5'5" (was 5" 8" before my spine started collapsing)= 125 pounds, plus 22 1/2 (5 for for each decade past 25), I could weigh 147 1/2, but I have to subtract for my small bones so I'm headed for less.
I still am more concerned about size. I need to fit in my summer clothes.
Just came in from walking the dogs. It is so pretty out at night. Now that I've caught my breath, I have an app't with my seam ripper. One whole row of the quilt I put together this afternoon doesn't look right. Note to self, do not quilt in a hurry!!
