Today, we assembled our equipment - old newspaper, small paintbrushes, keys and paint.
Covering the table with newspaper, the paint shaken and the correct key identified.
The key was painted yellow (we were lazy and didn't take it off the key ring)...
...and left to dry in the sunshine.
Once fully dry, it took about an hour, we had two sets of keys with a lovely bright yellow key for us to spot - effectively, a visual "USE ME" for all of us to see.
As shown in our pictures, we also use yellow wristbands on key rings as these allow the keys to be seen and held easily. J's getting used to using keys when we go on dog walks - locking the door and keeping the keys safe - and having a wristband means he worries less about losing them. Attaching them to his wrist gives him the security to know he has the keys with him and also has them readily available when arriving back at the door.
