This is an intermediate level pattern that contains written instructions and some photo guides for making a small or large size zippered pencil case with triangular shaped sides. The pattern process consists of working in rows to make the base, then working in the round with the lemon peel stitch to make the body. The lemon peel stitch is made by alternating single crochet and double crochet stitches, which gives it a bumpy, raised texture. The pencil case is finished by sewing a zipper at the top. The bag dimensions are 7.5 in. long x 2.5 in. wide x 2 in. high for the small or 9 in. long x 3 in. wide x 3 in. high for the large.
The pattern is written with US standard crochet terms and abbreviations and requires familiarity with basic crochet stitches (the single crochet stitch, double crochet stitch, and sc decreases), working in the round, picking up stitches along the edge of a piece and basic sewing skills for sewing in the zipper.
