Car Stitching

I am going to be in the car for a 3 hour round trip rather soon and have been looking through my stash for something suitable to stitch in a moving car.

My criteria for the project:

1. although I usually stitch on 36 or 40ct linen, car stitching has to be done on 28ct
2. a limited palette, no more than five colors
3. no blended needles or fussy specialty fibers
4. a fairly simple design or a design with a border that has an established repeat for mindless stitching
5. small enough to fit in an 8"  spring tension hoop for easy handling

So far I have come up with these possibilities:

This is Pineberry Lane's Mehitabel's Redwork Sampler.  Only one color, relatively simple in design and it calls for 28ct linen.

One of last year's JCS Halloween ornaments, this is meant to be stitched on a 40 ct ivory  linen but it meets the 2nd, 3rd, 4th & 5th of my requirements

This relatively simple blackwork design would work nicely with the above criteria.  It would also help to satisfy one of my annual goals to stitch a few more hearts for my anniversary and valentine's day tree.

Another heart design, a French style free chart, would also work though the word I would stitch would be Amour.
