I made it even BIGGER
Everyone loves the giant bag I made for my daughter when she was pregnant. It holds enough for an overnight trip or all the toys etc you need for the beach trip with baby. I added one row horizontally.
Fantastic bag!!!!!!!!!!!!!
I have made quite a few different styles and they are a BIG hit. I drove to Virginia Beach to get the magazine. could not wait for mailman.

Great bag ! I have sarted a secnd one already!
love this bag!
I have made several of these and also made a couple smaller adn in the process of making more!!!
great project
The results are stunning. Already made 2 of them, one slightly smaller. It's very easy to adapt to different sizes.
This really is a BIG bag. Fun and easy to make. I look forward to making it again with smaller squares and perhaps only using one piece of fusible fleece on the squares.
