Measured
I don't think I've ever made this much progress with a garment so quickly before. Only the right front and one more sleeve and I'll be set! I figure I should be able to get the right front done tonight and the sleeve done tomorrow... assuming I have enough yarn. Instead of knitting this morning I spent some time doing this...
... trying to figure out if I had enough yarn to finish the other two pieces. The side and sleeve I have made up now weigh about 2.5 oz. The remaining yarn in the color I need is about 2.75 oz, maybe a little less... my Ikea scale is probably not the world's most accurate weighing device. And yes, I am knitting to gauge! I'm thinking I should probably call Ruhama's and ask them to see if they have one skein they could hold aside for me, just in case.
I always wonder why pattern designers seem to underestimate yarn amounts... or cut them so close. I hate the feeling of not knowing whether I will have enough yarn to finish a project, especially when it could have easily been avoided. Maybe I am unusual, but I would much rather have way too much yarn and feel comfortable all the way through the project that I am going to be able to complete it, than always be worrying that I am going to have to be scrambling for another yard to complete something.

Oh wow! your top is coming along with giant steps :) Its looking very good and I love the color. I do the same thing with the scale and worry, weigh some more and then worry some more LOL. Almost as good as thinking about a new project :) Can't wait to see a picture of the finished top with you in it :)
Wow! You are really moving along on that sweater! I have to admit that I started working on that little Mt. Color bag yesterday. I was determined to finish SOMETHING before I started it, but it was my anniversary and I wanted to do something new and fun!
The little top looks fab ! Bet you can hardly wait to wear it ... well obviously ,as your knitting it so fast.
I ,too,like to have plenty left over.Nothing worse than running out.I always get an extra ball - mind you it's different for me as I have to upsize most things !
Kim Hargreaves patterns [Rowan] ,in my experience,tend to err on the generous side ;-]
