Pinterest is a place to pin images, not store data or info. If you click on the 'pinned from' text under the image, it may take you to the site that owns it and if there is a pattern there, you might be able to purchase it or download it. I would try googling 'Delectable Mountain Jelly Roll' pattern and see if one comes up for a "real" non-pinterest site. I have only seen Delectable Mountains made from large HST that are recut, not strips, but it should be doable.
