Yes, rigging is a seperate skill different from all other model building tasks. It takes practice, and you use the touch quickly if you are not constantly doing it. If I finish a model and don't do another right away, it seems to take me forever to get the moves right again. After about 30 minutes to an hour, I start getting the moves again, and the muscle memory kick in again. However, for a first rigged kit. I recommend you realize that rigging is likely to take longer than the entire rest of the build.
First, take your time and learn patience. Even today, after building sailing ship models for decades, If it has been awhile after the last rigged ship, I find, even after I recover my muscle memory, I cannot work on rigging for a protracted length of time. Too much concentration and fine manipulation are required. I never work more than an hour at a time. Any longer and my concentration will falter and my hands shake.
Also the right tools are important. I have two home-made tools I find essential. The first is a hook, about six inches long, made from a large, long needle like a chrochet or needlepoint needle, and cut the eye to make the needle. A chrochet hook is also okay. The other tool is a fork. I use one of those large sowing needles and cut the eye in half making a fork. Sometimes you need to push a thread between two lines close together, and that is where the fork comes in. Other times you need to fish out a line from an inner region of the rigging, and the hook is what does this. Vision aid is also a good idea- I use cheap readers from the dollar stores (now closed). I am glad I am in good shape for those.
Lastly you willl be tying thousands of knots. A bit of pratice, tying twenty or thirty knots in a piece of thread before even starting on the rigging is a good idea.
