Closing loop in sketch - need help

[JHT82]

I'm doing this logo for a client and I can't seem to close the sketch loop on the last part of the K in the logo. I've attached the files

Hi

You can Extrude all sections in surface mode, then create a Boundary Patch and Stitch/Sculpt everything.

you can do it like this

I used the Boundary Patch tool to find the gap in the loop.  Turns out to be the lower right corner spline, which is not connected at either end to the adjacent geometry (sorry, my images were captured looking from the "back" of the sketch):

   

I simply created a new spline between the two points, turned the original one to construction, and then dragged the two control points to visually match the original curve:

The repaired file is attached (Inventor 2017 format).
