My bad. The photo was labeled wrong.
You need 48 4-patch blocks that measure 4.5", not 96. Bad Judy! 98 darks and 98 neutrals to make 48 blocks. Sorry for the confusion. I just got home a while ago, long long day, and feel terrible about my typo on the photo causing angst and anxiety for everyone
And yes, the 4-patch with all the colored blocks is correct in needing 48 2.5" squares.
Mea culpea, no excuses for this.
