Polkaandbloom on Etsy sells unique and pretty embroidery patterns, all original designs and totally cute.
(In case you hadn't noticed, I like things that can be described as cute.)
The pattern shown here is called "Floral Vignette" and is perfect for a hoop mounted sampler.
She also sells embroidery instruction books, including one for left-handed stitchers.
She's in England, but most of her products are PDFs, so no worries about shipping!
