Hi Patt,
I'm glad my knowledge benefits you. One tip I'd like to share is that you might like to do a test first: before you varnish, give a gentle wipe on the painting surface with spirits (I used turps). If there are traces of paint on the wipe, then the painting isn't totally dry yet.
And not forgetting that after varnishing, place it with the painting face on the wall than right side up so that dust will not be trapped onto the varnish. Hope these additional tips help you further.
Finally, my thanks for your compliments. I continue to work hard and do the best I can
