Has anyone used the tufting gun?

Hello, looking for a bit of guidance on this tool. If anyone who’s used it is in tomorrow or Saturday let me know!

Thanks ‘

I tried and failed. But @mbg figured it out (double or triple down on amount of thread)

Yeah by the end I was loading in 4 threads at once, the gun still seemed to be snipping them off after max half a foot even then, open to any tips on here or in person!
