The umbrella's design is fairly simple. I can't translate all of it, but it's easy to figure out what to do using the drawings anyway. Here's what you have to do:
A + B ) You need 2 circles and one little square for the umbrella. First, you have to pleat both circles in the desired shape of the umbrella. Don't flatten the model though, so that it keeps its pyramid-like shape. Both circles should look identical ( except for the color, of course ).
B ) To make the pink thingy you have to outside reverse fold the paper along the red lines. Again, you shouldn't flatten the model, so that it looks like the drawing in the diagram.
Blue thing ) Make a prelimenary base ( step 1 - 4 ). Squash fold all of the flaps ( step 5 ). Slightly pull the model apart.
It should look like this now.It won't lie flat at this point ( step 6 ). After that you have to squash fold the 4 flaps inside the model, to lock the whole thing in place.
Part C should look like this now.
Assembling the whole thing :
Step 1: Glue a tiny stick to pyramid-like circle ( A ). Don't tear the paper though.
Step 2: You can use a tiny string to strengthen the tip, so that it's firmly attached to the stick.
Step 3: Turn the model upside down. You'll have to make a tiny hole at the tip of part B so that it can slide down along the stick.
Step 4: This is what the model should look like now.
Step 5: You'll have to make tiny tears in the paper now and fold the little flaps inside, so that it looks a bit more like a real umbrella. This also kind of locks part B into place. You can also use glue to attach the tiny flaps to part B.
Step 6: Turn the model back up again. Put some glue on the tip of the umbrella and attach part C to the umbrella. You can also use a string and wrap it around the bottom tip of part B. This will attach part B to the stick.
Step 7: Take a small rectangular piece of paper and put some glue on it. Now wrap it around the stick near the bottom tip of part B to lock the entire thing in place.
Step 8: Finished model.
PS, I'm horrible at explaining things, but I hope you'll be able to fold /glue it together now.
