Lattice and Solid Triangles, free patterns

I first made these triangles like these as part of a free sample pack I sent to my first customer. She wanted crochet shapes to add to her cloth books. Since then, I've been asked to write down the patterns, so I shall attempt to do so! Feel free to leave your feedback in the comments. I will be making these triangles into a pyramid toy for my son. For these triangle, I used a 4mm hook and brightly coloured 8 ply acrylic.
