Carol Philips has been making "prayer paintings" to count the Omer. Counting of the Omer, Sefirat HaOmer, sometimes abbreviated as Sefira or the Omer, is a verbal counting of each of the forty-nine days between the Jewish holidays of Passover and Shavuot.
The ground for Philips' pieces are used seed packets, since Omer counting is related to agriculture and harvest. The pieces vary in the extent that they relate to the meanings of the letters, the Kaballah, and other associations and thoughts.
To see the entire series, facebook friend Carol. She posts the image for each day and writes about the meanings and her process. The images here are days 5, 14, 18 and 30.
