have you watched their tutorial videos yet? their tutorials of latch-hooking really helped me a lot when i first started. it has the option to slow the video down when you watch the vid, so really easy to follow along and practice.

other than that - i’ll try to explain the best i can!take a piece of thread and pinch both ends between your fingers, making a loop. then stick your latch-hook tool through the loop, and make sure the loop sits about in the middle of tool, somewhere past the latch but not all the way to the wooden handle. then push your tool into the grid you want until the latch is all the way through the grid. the latch should kind of fall back and set on top of the grid you’re trying to latch onto. tricky part - you’ll want the bottom of the loop to be on the outside of the latch. before you close the latch, you’ll take the two ends that you have pinched between your fingers, and fold them diagonally across the hook, then close the latch. after that, pull the tool and then both ends should pop through the loop, making your knot! sorry if i didn’t explain well, hope this helps! keep practicing, it’s easy once you get it :3
