I can't believe how long it's taken me to get around to doing this tutorial. Apologies to everyone who has been waiting since.... July... oh my gosh, it's even longer than I thought!
Anyway, here goes: This tree is based on a simple teabag fold. If you take the time to burnish each fold it will make it easier for you.
Take one of the squares and fold it in half diagonally. Open it out and fold in half diagonally in the opposite direction. Open it out and fold in half horizontally. Open it out for the final time and fold it in half horizontally in the opposite direction.
Holding the folded square firmly by the bottom edges, press gently on the top edge to invert the fold.
Repeat with the other side, then fold down one of the front triangles until the folded edge is in line with the centre of the triangle. Repeat for the other side.
If any of your folds do not line up accurately, you can disguise the white edges by brushing with an ink pad.
Take the smallest tree section and attach it your card with double sided tape across the flat back of the folded triangle. You will see a 'pocket' for the middle tree section to slot into.
Assemble all the tree layers by slotting them in. Now you can add a topper for your tree, a star, bow or angel for example. A message tag or peel off may be used to emulate the tree trunk or just add a small strip of card.
Have fun making your trees. Try using patterned papers which you might not normally favour. They look completely different folded and you can achieve some good effects :)
