Gauge isn’t really important here, as long as you ensure that your hook, yarn and tension result in a fairly tight stitch. Using different yarn types and hooks can give interesting results and make a larger or smaller plush.
I highly recommend using the ‘invisible decrease’ especially when working in the round. While it’s not completely invisible, it does help to reduce the gaps that concentric decreases tends to leave behind. Overall, it just ends up looking alot neater.
