Bag of Sharing

This is a nonmagical backpack that can hold up to 120lb of equipment. However there are no openings on the bag it's self, but there are 6 patches on the bag. These patches can be removed from the bag and be attached to another fabric. When attached the patch becomes a 1ft long opening which opens into the top of the bag. The patch can't then be removed from the fabric without destroying the patch.
