If you have yardage concerns…. my “tip” for conserving yarn is to form the stitch on the tip of the needle rather than pushing through the whole needle which is my more typical “relaxed” style of knitting.

It is estimated that the last 3 wedges (15-17) use approximately 50% of color A.

After:
Wedge 14… 52g remain
Wedge 15….42g remain
Wedge 16….28g remain
Wedge 17….11g remain

I probably knit more tightly than I needed to, but better safe than sorry and
