I used a plastic cup to trace the two larger circles. (1 from the drinking end and 1 from the base)
I drew a large circle on my fabric and (slowly) began stitching around with the halves of the larger circles.
Making progress and it actually WILL turn out like it's suppose to. Shock! After a few circles in, I started to use the smaller halves of felt from the 2.5" template.
I carefully bunched and positioned the felt pieces with pins before starting the sew them.
