Hi Kath
My Mum is knitting a very similar pattern to that at the moment. But she is doing the pram blanket size. She mad one in cream last year for my grandson Freddie (we did not know sex beforehand). Now she is doing one in pink for my new grandaughter due in June.
As she is 90, she just picks it up and does a little bit at a time. Mind you she knitted a baby jacket last week.
Love the poncho D-Q
