OK I’ve measured and measured my finished sleeve and tried it on, and I’ve double checked all my calculations and…. I should have really just followed my calculations to begin with! Argh! I think it’s still too narrow. I should have started the arm shaping at garter ridge 17 like the math said to, even though the triangles looked mini. And I should have made the triangles to 21cm rather than trying to make the sleeves narrower.
I did find, after recalculating, that my swatch may have felt too wide for two reasons: 1) the math says the triangles should be 65 rows before joining in the round, and I rounded that up to 66 in my swatch, and 2) when I picked up for the lower filler triangles I didn’t pick up all the way around I left a gap at the underarm seam making the cuffs wider than they should be. Grr.
Actually, it probably would be fine in the end because it’s just a few rows different but this is where I really hate myself: I will have to start all over again sigh.
On the upside the sleeve length was almost spot on — when I do the math for 47cm total sleeve length with blocked-to-unblocked gauge I get 130 rows (vs 132 rows).
Here’s the FINAL plan (which is also pretty much the ORIGINAL plan):
- Knit triangles to 64 rows / 32 garter ridges / 33 sts per triangle
- Start increases for arm shaping at 17th garter ridge / when there are 17 sts on needle, next row (with increase) will have 19 sts per triangle
- Increases every 6th row 15 times total → + 6 sts by end of triangles = 39 sts per triangle total (should be an inc on last garter ridge)
- Join in round and continue to 132 rows / 66 garter ridges total, separating after 58 garter ridges (first separated row is last inc row, and 7 ridges more after last / 15th increase)
OK so here goes, hana hou!
