Thanks, KaTe, for being a great organiser, so why not go over to her blog for a visit.
I'm sure she would LoVe it!..
I also came across this information a few weeks back and have been meaning to share it with you. Of course all you talented and experienced quilters out there probably already know it... but I have always just added the binding usually at 2 1/2 inch for a double fold, without knowing there was a calculation to it. If you use this guide... it makes it easier, having had all the maths done for you. I found it great and have pasted it in my quilting info book.... but that's just me!
ALso a very big HaPpY BiRtHdAy to DD1.
Hope you have a GrEaT PiNk day K.
