Close to My Heart posted its retiring items list on my website under "Retiring Items".
Several colors are going away, including Buttercup, Blush, Twilight, Crème Brulee, and Sky. If you want reinkers or extra cardstock for any of these colors, I suggest buying them now, instead of later. These items don't usually stick around long once they've been announced.
Many more items are on the retiring list, including stamp sets and ALL of the paper packs in the current catalog. All of the retiring items are "While Supplies Last" and on July 31st will be completely gone.
