Any type of thread or yarn may be used to tapestry crochet this tote. If a thicker fiber is chosen, the hook should be proportionately larger; if a finer yarn is selected, a smaller hook should be utilized. The narrow oval spiral base is crocheted first, then when the diameter of the base is no longer increased, the edges of the spiral move upwards to form the walls. The motif is 24 stitches wide, so the total number of stitches in the base is a multiple of 24. It is possible to make a variety of sizes with the same design motif simply by increasing or decreasing the size of the base chain by 12 stitches. These instructions are for right handed crocheters.
