Best Playmat Trick!
If you intend for your playmat to stay in one place, as opposed to taking it apart each time you use it, here is a great trick!
Assemble the playmat and tape the seams of the back side - turn it right side up. Packing tape or duct tape can be used to keep the pieces together. This avoids any potential shifting.
If you are using the playmats in a higher traffic area or have an especially active toddler, having the playmat pieces affixed to each other can be useful. Businesses who use the playmats should definitely try this.
