1Drafting Shapes
Drafting shapes (necklines, sleeves) mathematically can be a challenge (especially curves).
Using Graph paper is a much easier and more accurate way to get knitting instructions.
Draw the shape on knitters graph paper, then follow the boxes along the shape to create knitting instructions. Each box represents one stitch and one row.
2Stitch patterns
To keep stitch motifs from being distorted, create the design on "to scale" graph paper. (no surprises after you knit!)
