Hi all...

Wonder if anyone can help....

In the middle of decorating my bedroom and would like to do the below
design on my back wall as a focal point but in different colours.

However, anyone have any ideas how to measure it out on the wall
before painting so as to make it look even?

Any help greatly appreciated.

Tie a pencil to a piece of string.
Fasten the string to the top of the wall with a drawing pin, near the
ceiling, with the pencil hanging down.
Draw your first arc.
Wrap the string around the pencil until it's about a foot shorter and
do the
same again.


Thanx for reply.

Am still none the wiser....wonder if it would alright with just equal
stripes straight across!!!

Anyway..

1) What length of string should i use?

I don't know, it depends how far down the wall you want the arc.

2) How will that make them equal in width

Because the string is always straight, provided you keep it tight while you
are drawing.

3) I'm being thick am I?! (careful with your answer)

Quite possibly, or maybe I'm not being clear :-p

Have you never seen a groundsman draw a large circle on a football pitch? -
or a semi circle?
He knocks a stake into the centre spot with a rope attached to it, then
measures out half of the width of the final circle.
Attached to the end of the rope is his whitewash brush and he walks around
in a circle, this is the same way you can do an arc....if you shorten the
rope/string you will get another circle/arc slighlty smaller than the first,
but equal
