Here is the pattern that I designed for my kid’s bath toys, but it is useful as any kind of bag, complete with an icord drawstring and a frill around the top!

It is a very easy knit, even beginners should be able to master this one.

Specific yarn weight, needle size and gauge are not critical (or even necessary!) for this pattern. You can use any that you like, keeping in mind that the finer the yarn and bigger the needles, the more open the mesh effect will be.
