Perfect Circles

I needed to make some circles. 

The pattern called for 7 1/2 inches.  That seemed a bit big to me.  So I started trying to find something to make a circle with.  For some reason I do not own a compass anymore. 

I started with a Solo cup.  But as you can see it is only about 5 inches and it doesn't look very round.

Then I though how about a paper dessert plate.

It is 7 inches but the problem is that the edge is rolled so it may not always end up so circular.

The inside of a painter's tape roll is only 3 inches.  Way too small. 

I had some circles which I had made to help mark a quilt.

This one is 4 inches.  Too small.

I thought this one was too small too.  Also since it was a paper circle I wasn't too sure if I wanted to use it because it is tough to trace around a paper circle without it getting a bit lopsided. 

I finally settled on this saucer from my dishes.   A little smaller than 6 1/2 inches.  Nice hard edge.  So I started to trace some circles.  And made this.

I finished it off with one of the sweet buttons that I got from Dawn in my care package that I received yesterday.  I am pretty pleased with how it turned out.  

I am thinking this is the best size and I will be making plenty more.
