I am new to paper models and I have finished one but the next one I want to work on is SSBB Yoshi ( http://papercraftmodels.blogspot.com.au/2011/05/ssbb-yoshi.html ) but I am having trouble getting started because I haven't made one where the pieces aren't numbered or have some idea of how they go together. My question is, when you have a whole lot of pieces with no instructions or numbers, how do you go about working out which parts are which and whether the score lines bend inward or out?
