Mom used her Viking to make a cover for her studio bed. She used upholstery weight fabric and made piping, The full Monty, as it were. She had no problems with her machine. But I don't want to take my chances with it so I brought in my Necchi Super Nova.
In order for it to function as a flat bed, vs a table top, in the Horn Cabinet I had to adjust the airlift.
It was relatively simple: loosen the 13mm nut, slide it to the proper position, tighten said nut.
Steven fashioned an insert from a piece of luan underlayment. It isn't quite thick enough but it will do for now. I can use this same piece as a template for an acrylic one.
I am now good to go. I have picked apart the seat cover on one of the chairs. After the bike ride today I can think about cutting out the pieces. (Yes Dre, I see the typo in the watermark)
