I'm going to start collecting bits and pieces for my seating plan as I see them in charity shops and boot fairs etc but not quite sure how I will assemble it. Have a look at my inspiration pictures below.... should I hang the small picture frames using nails just like you would on a wall? I'm worried that if they are balanced they might fall off but if I glue them down then I can't make any last minute changes to the plan if guests drop out etc and then can't sell the frames after we're done. Any advice greatly appreciated!
