Take a look at my friend Deborah's dot dabbers! She always inspires me!
I have always used bingo dabbers with my tots - but the ink does not wash off well. Getting the colours you really want may also be an issue - so to make your own is a great option!
Here is my version!
We used yogurt drink containers and 2 styles of makeup sponges.
The pink one is like a regular sponge - more porous.
The sponges were too small - so I added some fine netting and secured it all with elastic bands.
They worked out great! One had a bit too much water
