Here are some of the tools that can help (although not required) when building CraftClub.
Plier
There are many small joints that need to be folded when building CraftClub. Having a plier, especially ones with bent tips, is extremely helpful.
Round rod (brush, toothpick, etc)
Brush is handy when moistening small areas, and the grip can be used to push the paper against it to give it a curve.
Sand paper
When popping out CraftClub parts from the original sheet, sand paper can be used to smooth out the edges.
Rulers and clip
To make a clean edges when folding flat, such as on the wings of a dragonfly or beetle, put the folded edge between the rulers and use the clip to hold them together while it dries.
Super glue
If you have trouble keeping the joints together, try putting them together with Super glue or similar fast adhesive. It can also be used to affix the built model to the display mount.
