Wet felting a landscape

I had asked for Moy Mackay's book on Felt & Stitch for my birthday. It is even more lovely than it looked on the Amazon site. I have a ton of wool roving, although it is amazing how much white I have gone through since it is the base for all the pieces.

I forgot to take step by step photos. I put down two base layers of white roving,  the second layer is perpendicular to the first.  I then used colored roving to "make" my picture.  I used blue roving and some blue silk hanky (the darker blue) for the sky. I added some green tencel or bamboo to the green roving for the grass. I don't know what kind of wool the black was, the fibers were really smooth, maybe it was merino? The reds are a hodge podge, I had bought some fiber packs that had curly wool, angelina etc mixed in it, as well as adding wool and more angelina from my stash. There are at least 6 different fibers in the red section. I did include some Nylon dyed fibers, but they were molting off the piece when I was felting it.

Here it is prior to felting. 

Moy used a bamboo mat and garden screening for felting, but I used bubble wrap and fine tulle.I place tulle over the whole thing. I poked holes in the waterbottle lid and just used 1/4" of dish soap with 1/2 bottle of hot water.

Moy used a ribbed rolling pin, but I used this firm plastic roller someone gave me (for polymer clay?).  After the rolling pin, the whole thing gets rolled up and rolled a lot, rotated 90 degrees and rolled, again, and again, and again.

Here it is after the whole felting process. I plan to do some machine and hand stitching, as shown in the book.  It has a rippled texture on the whole piece that I don't quite like. Does anyone know how to prevent this or fix it?  Maybe it was the bubble wrap. I will try to find a bamboo mat and see if that prevents it on the next one. I will try to take some better pictures next time the sun is out.

I also did some cherry blossoms. This one did not turn out as well, but I think with some machine and hand stitching I can give it a wow factor. I feel if I had used a blue sky it would have had more pop.

I cut cherry blossom shaped out of roving, but they lose there edges after felting.

 The ripples are driving me crazy. I need to find a way to unripple it.

I plan on doing some smaller abstract pieces next week, if I can find space to do it as we are renovating the kitchen. Eeek!
