3 yard quilt is a easy one goes together quick

Radiance by Villa Rosa is my new favorite. I made 2 this week for new additions to the family. With a focus fabric and 2 coordinating fabrics, they are super cute.

The easiest go-to baby quilt for me is this one. It is quilt as you go so when you are finished sewing all the strips together the quilt is done, and ready to bind.

There's also the stand-by of using a panel with some cute borders. There are so many adorable kid's themed panels out there!

Lone Star Baby quilt by Amy Smart at "We all Sew", finishes 40 in. Sq. (Easy to add borders to)

'quilts for kids' website has a few free patterns...each can be done over a weekend at the longest.....

Thanks for this link, mandyrose. It looks fast and easy and a good scrap buster. Must try this one, or two, or five, or 10.

Thank you all for the great ideas. Can't have too many options for children's patterns.

A checkerboard! I love it. I have that stripe fabric that you used for a border, too. It makes a quilt look so happy.
