This is super frustrating!
I hadn't posted for over a month and now I discover that I can't reply to the comments my friends left on my post of yesterday.
Perusing the Blogger forum reveals that I'm not the only one; this issue has been around for over a month, and, as far as I can see, Blogger/Google seems to think it's been fixed!
I'm seriously looking into the options for changing to another blog provider.
Update 29 June 16:45 CESTThe issue is solved!I just received some email notification of comments to this post. So I'm no longer thinking of moving my blog. Everything seems to be as it was.
I'm very grateful to the people who helped me with this today. All the useful answers came form other bloggers. The authorities at Blogger were not at all helpful.
I'm grateful for your comments and have seriously considered your advice.
Circles it is, but with a change of scale.
And so to sew, but first rip off that plain white border and then add more print border. As the weather is beautifully warm I shall be appliquéing circles while sitting outside on my balcony this afternoon.
