...or to the beach.
Plymouth Yarns Fantasy Naturale Market Bag (free pattern). I used nearly all of two hanks of "Fantasy Naturale," a mercerized cotton; a pair of 10-1/2 US straights and a 15US circular; and I think it took about a week to knit (with breaks). I made one mistake in the pattern toward the top, but it isn't obvious, doesn't affect the function or compromise the strength of the bag, and no one would ever notice -- so "design feature" it is, making the bag my own. ; )
It is shown, at top, holding three BIG boxes of cereal with room for more -- perhaps a fourth box of cereal and a loaf of bread on top. There are four towels in the bag at lower left, with PLENTY of room for more towels, sunscreen, lotion, a book. One of the things I like best about the bag is the garter stitch square that forms a solid bottom. Any dishcloth cotton would make an excellent, very affordable substitution. Great pattern.
