How do you wash your blankets and wraps? 
Machine wash separately on gentle cycle in warm or cold water. Although the blankets can be tumble dried on low, we feel the wear and tear on your dryer may suffer due to the weight and recommend line dry.  If your blanket has bright colours that might run, wash the first time in cold water with 1 cup of salt to set the colours. 
For flannel, use fabric softener or 1 cup white vinegar in the rinse water to soften flannel and help remove pilling.
