The ecv back of the rentals from walker, are easy to make the slip cover, because its just a simple pillow case type cover.
Then I have a Disney embroidery machine, and I made disney squares (with a different character on them, in a contrasting color. Then fabric glued them onto the felt slip cover. If you can sew. Using felt is easy because it doesn't fray and fairly sturdy.
You could also get the disney iron ons, or are they called appliques? Like at joann fabric - don't forget the 40% off coupons in the paper, or get their app and get digital coupons.
Then use a fabric glue and glue them onto some felt. Making the embroidary designs with my simple machine took a long time, but I have used it multiple times.
I even made something for my stroller so that it is easy to recognize.
However in the warm months the felt doesn't keep you cool if it touches your back. If it looks like rain I take it off in the morning or I fold it up and it get put away if I'm out.
Just remember to bring along whatever your planning to fasten the sign or creative thing you make. Then if it is or isn't water proof depending on the season you might want to make sure it can be removed, and stored so the hard work doesn't get ruined.
It does make finding things easier in the sea of
