I do like the look of these roses without a stamp because they really enhance the romantic look for this set.
I'm not as fond of the word stencil background provided, it's ok enough to make out the words a bit but I'm not yet sure how I'll use it for a background based on the way the words turn out a little thicker looking when inked. I know the point isn't for them to be readable, but I think it would look better with the text being crisper when inked.
The stencils alignment is ok, it may take a few tries to get it really perfect and closer to how they display the images on the packaging. I personally think that these stencil only sets should be made with full border markings to assist with alignment. This set has a few, but you will still have to adjust the stencils to get them to work out like they should.
