What are some preschool Valentine's Day crafts for 4 year olds that don't require anything that requires drying time (paint, glue, etc.) and any supplies I need to save up for in advance (i.e. empty water bottles, toilet paper inserts, etc.)? Should take about 10 minutes to make. I am already planning on having them make a little hat but need something else to fill up the 20 minute time allotment. There are surprisingly few ideas that fit this criteria on Pinterest!
