Drying 
Line drying your shells will extend the life of the velcro significantly. The high heat of the dryer can cause the velcro strip and laundry tabs to get fuzzy and worn out very quickly. The diapers can be “fluffed up” by putting them in the dryer on low after air drying. It’s okay to put the diapers in the dryer on hot for about 10 minutes to seal the seams occasionally and when necessary.
