Thanks for posting that, @stella tella - I had a quick look at the BBC Cymry Fyw website with the vocab button, and it looks like a great resource.
You might like to look at Lingo Newydd. It is a magazine for learners published by Golwg. The articles are color-coded to indicate difficulty (starting to learn, more experienced, very experienced). Each article is accompanied by a vocabulary list. It’s not a big magazine - the Dec 15/Jan16 issue is about 20 pages - but there is no advertising, and it’s quite a bit of content. Unfortunately it is expensive to have it shipped outside of the UK. I am lucky because Sion Corn was very good to me and got me a subscription 
I have also recently finished reading “e-ffrindiau” by Lois Arnold, which is fiction. It was written for learners and has vocab at the bottom of each page. It is written as a series of e-mails between two women learners, and as such, gets progressively more difficult as the book goes on (and the learners learn more). I enjoyed it very much, and learned a lot of vocab. It would not be too hard for you.
I do use Memrise, but I agree with you that a lot of the vocab learned that way doesn’t really stick - at least not until I can use it in some way. I have been keeping a written journal in Welsh since November, just writing a simple paragraph or two about my day, and that has been a good way to make some of the words learned via Memrise, and words looked up in the dictionary, stick in my brain. I also make my own Memrise course out of words I keep hearing and don’t know. I seem to retain those better, probably because I chose them 
Watching S4C can be an exercise in frustration, because it makes me realize how far from real-life comprehension I really am, but I love being immersed in the language and I am seeing myself make a tiny bit of progress, I think. I do really enjoy some of the programs. Wish I had more time to watch!
I had been listening to Radio Cymru a lot more previously, and I need to get back to putting that on in the background when I am doing other things like eating lunch or cooking supper. Lately I’ve been listening to Welsh music instead, which has also been a good way to learn vocab. I find that as time goes on, I can pick a new word or phrase out of songs I’ve already listened to many times, which is always fun.
Ok, I rambled on enough! Diolch i ti for sharing your experience and resources.
