A quick note to say I got the pattern dmc 3865 suggested. Yeah, it is fleece color but it disappears into the fabric. Just too light. So I am trying dmc 168, which is a bit more silver / gray. Above I have stitched just a few sheep, and I think it is fine. But if I don't write the number here - in a day I will drop the floss into the sofa never to be found again, and not have a clue what the number was.
And the colors on the house - dmc 221 is the red, 310 black, 3790 window sides, which is also the odd color sheep floss color.
