Pattern help
Welcome to KH!
Can you post a few lines of the decreasing? Don’t post a large portion of the pattern due to copyrights.
Usually with decreases in a fancy pattern stitch or even k1p1 rib, you need to give up all or most of the repeat when you work the decrease. Work the other sts in stockinette if that’s appropriate until you can get back into the pattern stitch. You don’t want to let the change in stitch number throw off the columns of the pattern stitch.
