I started this lino etch while the frogs were croaking and rain was still falling. But now we seem to be back to the hot weather, at least for the moment. I have used the frog image to experiment with caustic soda as a means of etching into lino rather than carving. Quite happy with the results particularly on the branches that he is sitting on. It does require some time waiting for each etch to bite into the lino, and you are not always sure how deep it is etching, but interesting effects to be gained.
Here are the images as it progressed.
