Author oklahomadawn says: As of today's date, Sept. 24, 2014, the SBF download collections that can be used are: Falling Leaves collection, T.G.I.F.~This Grandparent is Fantastic, Back to School and Friends Forever (this last one is okay because it was available free when this challenge was scheduled). If a new designer collection is added before the challenge starts you can use it as well as the 4 collections mentioned above. :) Sep 24, 2014
