Sweater Knitting Helper

A Flask web application for quick sweater planning calculations.

Inputs

The UI collects:

• Stitch gauge (stitches per 4 inches)
• Row gauge (rows per 4 inches)
• Neck circumference
• Yoke depth
• Arm circumference
• Chest circumference
• Desired ease

Calculations

• Stitches per inch = stitch gauge / 4
• Rows per inch = row gauge / 4
• Total chest stitches = (chest circumference + desired ease) / stitch gauge
• Armhole stitches = (arm circumference + desired ease) / rows per inch

The app also shows rounded stitch counts for convenience.
