Nice Bulletin Insert Explaining the Place of the Gesimas in Lententide
Look at
THIS BULLETIN INSERT that Rev. Todd Peperkorn has made available for everyone's use at HistoricLectionary.com.
If you're like me and don't want to have to reinvent the wheel, this is a great summary. The insert states that after Ash Wednesday the crosses are veiled. I always thought that ceremony was after Judica. But since he makes it available in both .PDF and .DOC formats, it's easily changeable.
