Hello my advice looking at the picture. Would be to find a pattern for tote bag with pockets. And just make more pockets. Double the pockets and halve the distance between each pocket.
Well I had to google that one.
1. Here is a bingo dauber bag that is not free so that others might know what it is.
I couldn't find a free one sorry.
Sewmom I had googled in the past and could not find anything either for a pattern. H&*
