A vacation project I couldn't refuse

Dear son needs cushions from his boat re-covered and I've "got the time this week"...lol
We're talking garage here for enough room:

No it's not a small boat, and these are not small cushions...we bought 10 yards of fabric and I need at least 2 more. (See the slab-like things behind the 'cutting board'?)
Yup.
"Cushions".

I said I'd thought I would have different sewing projects in my future...like little kid clothes...so he said they'd work on kids if I'd do the cushions...lol
