Any type of thread or yarn may be used to tapestry crochet this bag. 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 star repeat is 13 stitches wide to commemorate the first 13 states – and altogether the bag has 50 stars. Since the motif is 13 stitches wide, the total number of stitches in the base is a multiple of 13. 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 13 stitches. The charts and instructions in this pattern are for right handed crocheters.
