Embroidered Pillowcases - Part Two

You may remember my earlier post about my white on white pillowcase stitching project. 

Based on some helpful advice I received in the comments of that post, I decided to run a test before I started.  I needed to make sure that I would be able to see the white stitching against the white fabric and that I would like the white on white look.   

So, I did a bit of testing on the fabric.  I wanted to try both six strand cotton floss and cotton perle floss:

First is the six strand cotton floss - stem stitching:

Next will be the perle cotton:

Here they are side by side for comparison:

And a little closer look. 

I like them both and think either would be fine to use, but for this particular application, I prefer the flatter, smoother and silkier look of the six strand cotton floss.

I also tested the six strand floss using the satin stitch.  I am very pleased with the result:

Now for the border motif.  I have narrowed my choices down from these :

To these two.  I am about 99% sure I will choose the flowers!
