Mum loves anything with sheep on, so for Mother's Day I bought Rob Ives' book Paper Automata: Four Working Models to Cut Out and Glue Together and made her this Hopping Sheep model, which is now living on her dressing table.
It took several hours to make, and you have to pay close attention to the instructions when cutting, scoring and gluing (I used double-sided tape and a glue stick rather than runny glue), but it wasn't as hard as I thought it would be and I'll definitely being making more.
Rob's new book Paper Engineering and Pop-ups for Dummies is just out and looks fab. Once I've made up a few more kits it'd be great to learn to design my own automata!
His Flying Pig website offers some kits as free downloads, and has loads more for sale, as well as a whole section explaining the basics of mechanisms and movement and tools and techniques. Rob also has a blog where he shares his workshop notes.
