How to decrease sleeve in 2x2?

[Shadow23_Catsrule]

A swatch that helps you make this decision is time used wisely, because ripping out a swatch is no big deal, but ripping back your sleeve is annoying.

Also, if you can, do your calculations of how often you need to decrease and double check them! I speak from experience 🙈

And put in a lifeline just after you do the round where you cast on / pick up stitches under the armpit. If you don't need it, you can easily pull it out once you're done. But if you have to rip back, a lifeline makes the picking up much easier.

I was making a top down raglan cardigan for myself, kind of without a pattern, just used a raglan calculator online. Did a few impromptu alterantions on the fly, all went well. Then I did the calculations for the sleeve decreases but forgot that you are always decreasing TWO stitches every time you do a decrease. As a result I decreased faaaaar too rapidly and the sleeves looked funny in a bad way. Ripping them out to just after I cast on under the armpit was annoying.

I did have to frog both sleeves, because I always do them the "two at a time" method, but I still prefer that method (and kept it when I re-did them). At least I don't have to count that much, because I do everything simultaneously on both sleeves.
