For these Psalms I have used the week twelve DLP prompt of "cut up a magazine - add" and made two collage pages. I needed a change from inks and paints, nothing like a bit of cutting and sticking to ease the mind. Also amazing what you come out with in the end.
For Psalm 18 I focused on the word "Fortress" and sifted through my magazine folders for pictures of buildings and castles.
For Psalm 19 I focused on God's creation, mountains and sky.
Really glad I keep magazine pictures which "speak" to me to sift through when the moment comes.
