Check out this whimsical Crochet Checkers and Mushroom Bag. Pretty unusual and generous to hold a crochet bag. Life is too short to be the same as everyone else.
This is done in tapestry crochet techniques that partially hide the colour to form the checkers you see. The mushroom is done as a motif, in the end, to add on. If you don't enjoy the mushroom, don't do it. You are the artist to decide what you prefer.
This bag uses Red Heart Super Saver in four different colours.
If bags are your thing you prefer to crochet, one of my favourite bags that is bigger than you think is the lunch bag. A tutorial is available. I liked the hardware with the handles. Compare the fruits in the picture below to gauge how big this is. I was pretty surprised. These are the Crochet Lunch Bags.
