I can research it on the Internet.
I found a pattern. Jan Andrea at http://crafts/sleepingbaby.net/cart_cover.html.
But it needed interpreting. Not that Jan was complex, it's just that my mind seldom goes to it's technical side. That's where Poppy comes in. He immediately drafted a paper pattern following Jan's suggestions and then handed it over to me. Okay. It looks a little ghost like and even cutting it out, I still didn't know what I was supposed to do with it. I figured it would eventually hit me.
Eureka! The brain cells cooperated and the necessary sewing was figured out and a trip to the local grocery store for a fitting and off to Cincinnati it went! I read all the instructions and agreed with Jan that a little tote bag of my own design would be nice to transport it. And provide a little extra seating padding on the cart seat for The Viviers. We are ALL about her comfort....
Here she is at a restaurant with Mama and Daddy, happy as a clam and cute as a bug.
Here's to sewing for grandchildren!!!
