Half a page for each drinking straw
First thing I did the long oval base 20 cm wide and 9 cm, then your round with a diameter of about 9 cm.
With 23 straws folded in half, I formed a pasting range well all the points between them.
At the center of the fan I glued the round, Obviously I made another one almost exactly to the other side.
On the back I reinforced the center with a round card pasted.
I glued with plenty of white glue the two fans on the sides of the oval and waited to dry well.
I made so many wheels of two measures and I pasted them as you see in the picture.
I colored the entire napkin holders in and out with acrylic colors trying to give some shade similar to wood.
I have given then two coats of glue diluted to 10 x 100 with the water, this will be the paint and at the same time will make my much more solid door-napkins.
Finally I decorated one of my farfallotte salt dough.
