Glad to hear you've finished!
Just because of the way they go together, it's kind of odd doing it the first time, but then you catch on and can turn them out in much less time ><
" is it ok to clip into the seam allowance or in the future should i be clipping outward?"
I always do notches outward. If I cut into the fabric I know there's less of a chance of reviving an error if something does go wrong. Plus somtimes I cut my notches a bit longer, and if it's so long that it ends up past the seam allowance, then I know I'll end up with a tiny hole ><
