How to make your own spider web
First you can start by cutting a square wood piece. For this puzzle I used a square wood piece 60 x 60 x 8 mm. Dimensions of this puzzle aren't critical. You can use any dimension according to your materials. I can say only min. 50 x 50 and max 75 x 75 mm may be a good dimension for playing. (min 2x2 inch and max 3x3 inch).Wood thickness may be between 6 - 10 mm.
The template (Drawing 2) is for 60x60 mm square. You can save this picture, scale and print according to your material dimensions. After cutting a square , I cut four corners with a hand saw. Green lines show the outside of your square and hole centers. You can drill 10 mm holes (may be between 9-12 mm or bigger for a bigger puzzle). After sanding, you can draw your spider web and spider on the wood with a ball point pen. Don't use ink pens. If you have a wood burning machine, burning on wood is the best way. And don't forget adding feet for spider. For finish I applied a kind of lacquer mixed with thinner with an artistic brush. If you like you can use spray varnish.
And third drawing show rope arrangement. You can use a non elastic thick rope about 3 mm diameter. Beads must be bigger than your hole diameter. If you can find some wooden beads looking like a bug egg may be look better.
I used a small wooden ring. But you can use anything that you can find. If you like you can fix a small plastic fly on the ring with glue. Plastic flies are easy to find from fishing suppliers.
Take the loop 1, pass it from the hole 2 and after over the bead 3. Pull it back from the hole 2 and now the ring is free
