Wow, I think I have found my favourite card challenge blog - clean and simple! It is called CAS(E) this sketch and again, is a sketch challenge - but a nice, clean one. You can find all the details here.
For their Sketch 76 here is my card:
Hostess only set.
The only other thing I wanted to point out is that the bases for all the cards I have been making lately, I have been using the Value Packs of 5 1/2" x 4 1/4" card bases with envelopes. These come in a pack of 50 in either the white or cream and are so handy and time saving.
