This was another of the classes at Autumn Escape 2016 where the wonderful Vicki Boutin showed us how to made our own stamps from foam and integrated them on a layout. So in the photo below my stamps are the large pink rose in the lower left side and the couple of green leaves. The amazing thing is that I don't think they look out of place at all!!
The possibilities for this method are endless - you don't even need to be great a drawing (I'm definitely not).
