Amanda of Ryleigh's Room! She guess 298 leaving her just 26 off the actual amount of button pieces at 324!
Robyn of Jewelled Trellis was a close second, only off by 28!!
So Amanda drop me a line at Badge Reels and choose your id holder/keychain!! :)
Yup, 324 button PIECES fill up that bowl. And yup, I will use them ALL!
Thanks to all who entered! :)
