Best way to create a closed surface from these curves?

I’m currently lofting each pair and joining them but that comes out a little messy. Is there a better method?

Thanks!

Hi Weston - it might be messy - make sure you line up all the seam points - but lofting all should work. Check the Rebuild (maybe 15-20 points by the look if it, just guessing) and Refit options in Loft - Looks like it will be open at the ends though -
