Holes in the woods will do by using one slim drill, and where you will need to carve to create pockets eg for use candles or special chisel or a flat blade screwdriver and hammer. To add rope or wire line on the wood structures like the boats, nail the points needed for a nail to fasten and for glue wood together will need a good general purpose glue, especially in small structures not need to be qualified for wood.
In any kind of wood can give “aged” look, simply swipe it with a brush and white paint before it dries completely rub with sandpaper removing locally the most of it.
Such constructions either exclusively or combined with wooden shingles, shells, rope, cloth, burlap, wire, or any material you want, have almost zero cost, the process to build it is not difficult at all and even the simplest creations are an excellent idea for gifts.
