We worked on our cactus line art during #sticktokindness day, but this is a low-prep, calming craft for any day. I print on astrobright paper for black line art and we use black papermate flair pens or fine tip sharpies. Another option is to print on white and have students use thin colored markers. I challenge my students to use only straight lines. I don’t allow students to use rulers. This is a great art project for students to work on quietly as you read aloud or play music!
