Helpful Tips
Raglan Increases: The A.1 pattern creates decorative lines up the raglan. The yarn overs on either side create the increases.
Magic Loop: If you prefer, use one long circular needle (80cm) for the entire project instead of switching between circular and double-pointed needles.
Even Increases: To space increases evenly, divide total stitches by number of increases needed, then increase at those intervals.
Blocking: Gently block your finished sweater to even out stitches and achieve the correct measurements.
