Would you also like to crochet around a bag, but do you choose to use your own material? Then you can pick up the single pattern of ‘The Mexican Dream’ here, and get started with the extensive instructions. In the pattern it is assumed that the bag tapers down, and that the bags size can differ. Because this variability is taken into account with the pattern, it is perfectly usable for your own bag, granted it tapers down.
The pattern is written in US English, with crochet charts and several photo’s for the extra support.
