Another one for the bambinos, but young toddlers (1yr-18months) will enjoy it too. It's a lot of work to set up even though it's extremely simple, but mine took about 2 hours to do. All you have to do is stick items with different textures onto some sturdy card stock. That's it.
You can staple it together into a book (don't forget to put duct tape over the spine to protect baby's hands from the staples), join it with binder rings, or use a bulldog clip to hold them together so you can take them apart and rearrange the order of the cards, or take a few out at a time (that's what I did).
These are the cards I made for Ava:
On my cards I had satin ribbon, ice-cream sticks, netting (from cheese bags), foil, buttons, pipe cleaners, scrunched up paper, foam which I cut into underwater shapes, felt pieces, bubble wrap, lace, pom poms, and leather pieces. You could also use shells, fake flowers, raffia, wool pieces, fabric scraps, feathers, corrugated cardboard, paper clips, leaves ... whatever you can find!
Ava LOVES this book! She's quite rough with it, as she's still learning to control her little hands, so I lay her down for tummy time and lay a few cards in front of her. Eden and I talk to Ava about what's on the cards (what colours we see, the shapes, how it feels - rough, smooth, strethy, soft, etc). If you wanted to, you could also hot glue your textures onto cork coasters, or into a scrapbook, or onto the sides and lid of a box. Babies love to explore through touch, and this provides a nice sampling for them. Good luck!
