I've been experiemnting too and so as Annabelle said, there are so many digi tricks that each day is a learning experience.
I tired out another blending technique yesterday with a LO and I so love the results of it!
There are so many ways to blend photo on a LO and the one I used yesterday was the one that you can still see the sharpness from the photo, but only the edges are blended on the LO.
I haven't planned it that's why the result was a pleasant surprise.
Have a great day,
