one of the easiest ones I have is to make the chain the desired length.....turn.....ch 2, in the 3rd stitich from the end 2 dc, chain 2, 1 sc in the same stitich.....continue that until the end of the chain....turn.... repeat the pattern in the ch 2 space, continue until you have reached the size you want. Repeat pattern on the beginning end just one time, both ends will then look the same. Sometimes I go all the way around so all four sides look the same. Its very easy and its a warm one.
