<p>I second sobo glue. Also, if you plan on using foamboard, and none of the glues seem to be working, don’t resort to superglue. Most superglues dissolve the foam core. Might as well use a glue gun.<br>
Like sashimi said, it really does depend on what you’d like to express thru the various materials; it’d be rather hard to simply suggest different materials without seeing the design, or your knowing your thoughts and reasoning behind it.</p>
