This idea was that we would have Velcro that is attached to a sock with fabric glue and with you put them in the laundry stuck together and they would come out together. 

here we have two different way being tested one with fabric glue and metal snaps and one with sewing and snaps. over time I would go with the sewing method since the glue would deteriorate from the hot water. 

This idea, we had small magnets that we put them on the sock with fabric glue, the same thing with the snap idea over time I would find a different way to attach the magnets onto the sock

This idea is where the fabric is magnet infused so when the fabric is touching each other it sticks together
