xor - logic goat
DESCRIPTION
XOR - Logic GoatTRANSCRIPT
You will need a craft knife or other sharp knife, a pair of scissors, some glue and a glue spreader.
The best type of glue to use is white school glue (PVA.)
Print out the parts sheets onto thin cardboard. Photocopier card is ideal. Notice that the parts pages are marked front and back. Print out a front page, flip it over, then print the back onto the same sheet. Leave the ink to dry completely before continuing.
You’ll also need to print out parts page three onto paper as the tongue needs to be flexible.
Before cutting anything out, score along all the dotted lines and cut out any holes with a craft knife. Both these jobs are easier to do on full sheets of card.
Dashed lines are hill folds, dotted lines are valley folds. Cut along the solid lines. Grey areas show where to glue
