Childrens room-Ideas for making bubbles on a wall

Drop any round hollow surface in paint, (empty cans of vegetables, juice cans, any thing round!) remove excess by stamping it on paper towel or paper plate and press against the wall. Perfect circles!

You can vary the sizes & colors, over-lapping some. You can get a slightly variegated look by filling a disposable tin pan with several paints. The trick will be to not overload the stamping surface so doesn't drip. Good luck!

Blowing bubbles or texturing a wall?

Use the balls in the ball pit, paint if desired, stick onto wall using velcro, 3M temporary glue, (wish I knew what the glue was that comes on credit cards and advertisements) or something that you can remove later when they decide it is too young for them.

I have never done this but sound like good idea and opportunity for experiment, I would try foam or sponge different textures and conductances cut it in to shape and size you wish. Maybe pole fill batting you can be creative I may try this it grand baby's room like it. Thank you

You could use some clear plastic balls like this: https://www.consumercrafts.com/store/details/catalog/seasonal-clear-glass-plastic-ornaments/1105-89 and paint some transparent iridescent paint on them.

Kelly like the ball idea the children could make game sticking balls to wall.

I would get the clear plastic balls in different sizes too

We look forward to seeing pictures of what you decide to do.
