Day 281 - Lamp Shade Covering

So my sisters and mom are due at my house for an annual gathering in 2 weeks.  Last year we were trying to get the 2nd bathroom in the basement finished before they came.  I was going to get this lampshade covered and some wood hold buttons in place in the bathroom before they came this year!  I have a vision in my head of how I want this lampshade to look and can't quite figure out how to do it.  Tonight I worked on a pattern.

This is where the lamp goes and the fabric I will make the cover out of.
