I'm planning on helping my girlfriend install new vinyl in her long,
narrow kitchen. It's 24' long, and about 11' wide (at it's widest).
It then narrows down to about 8' where the cabinets are located.
Think a thick "T" shape like this

I understand vinyl comes in 12' widths, so we should be able to do
this without a seam, but I'm wondering the best way to lay out and
trim the vinyl. She has no other room in the house where we could lay
this out flat to trace a template, and it's 20 degrees outside right
now, so I'm thinking we can't drag the floor to the garage either, or
can we?
