Sewing - Hexagons

The hexagons are sewn together... some better than others.  I need to remember to pull the whip stitch tighter.

I now want to add some applique...

I'm not sure how I'm going to add them...  I had thought I would use brightly coloured embroidery thread and use blanket stitch, running stitch etc and possibly add some further embellishment.

Looking at it, I'm now thinking I will simply 'circle' the flowers with black thread...
