So heres what I used that charcoal thread for. Thanks for the help Dan.
And I finally got started on my seats. First set Ive ever done besides this barstool I used for a little practice. Used the barstool to help me practice with sewing with sew foam. The insert on the barstool is actually recycled leather from the original f150 seats.
Covers not fully installed on the seat in this picture, didnt have my listings sewed in yet. But I should have some finished pictures in a week or so. Im really happy with how theyre turning out, didnt expect it to come out so nice.
