This is major - Daniel Mitsui, one of the finest Catholic artisans or artists working today, has made CATHOLIC COLORING PAGES available.
Adult coloring books are having a moment, and these pages, which he offers, soli Deo gloria, are as beautiful as anything you will find in the collections at art supply or craft stores.
And he has made them freely available if - you cannot afford to make a donation. (But you should, if you can -- consider donating.)
The thing is, anyone looking for coloring pages for children knows how awful most of the religious stuff out there can be, not good and interesting enough for most past kindergarten age, and often grossly unworthy of their subject matter.
These are quite, quite magnificent.
