Identify them, make sure you know whether it's pinus pinea or pinus halepensis. It's very, very, very rare for any other species of pine to keep juvenile needles (fleshy, soft singular needles) that high up, so it's probably either of the aforementioned.
Then consider waiting until autumn to wire them into funny shapes.
Then from there on forward, you can make a plan for the next stage.
Consider looking at some scots pines too, as they are well adapted to your climate and probably easier on the adult vs. juvenile needles.
