What are you most proud of? That the girls loved it so much they decided to keep it for their bedroom... instead of smashing it up ! What advice would you give someone starting this project? Have plenty of newspaper, you will probably use more than you think & plenty of plain flour... mix it with plain water as you need it ~ the more flour the harder the PM (papier mache) will be... the thicker the mixture the better. Use any shapes, like lemonade bottles, as forms for the separate parts. The papier mache parts can be cut off the shape when hard & taped back together. I used baking parchment (greaseproof paper) to cover my shapes before I papier mache'd them & it worked very well. (the papier mache came away from the the shape very easily) The main castle body was made from cardboard boxes that I shaped, then covered with baking parchment & papier mache'd on top. I the removed the cardboard boxes, when the outer shell was hard, & attached the turrets to it with hot glue & masking tape before PM'ing the joins. Give your self plenty of time for the separate layers of PM to dry, if you don't the piata won't be hard & won't break when the kiddies try & smash it. Make a hatch for filling the shape with sweets & small toys, this can be taped back into place before the big event, so that it doesn't show. if your piata is big (like this one was) make sure that the fishing or strimmer line goes through, underneath & back through the shape ~ this will support it while it's hanging... the line won't be visible as you will decorate over it... I hot glued mine in place before decorating. I used the PM paste to attach wrapping paper to the main castle shape before applying fringed tissue paper to the turrets. The doors & windows were cardboard shapes, PM'd with tissues paper & PVA glue & then decorated, before cutting out & sticking to the castle. The flags were just PM'd tissue paper & again I used PVA glue. The PVA dries clear so although the tissue colour is a bit darker it retains is semi transparent appearance. Well... I think that's it... have fun & above all experiment... if your project is different than some one else's it makes it more interesting !
