Turning Twenty works well for FQs. The pattern book has directions for several different sizes. Plaids, stripes, camo, sports-themed fabrics work well for teenage boys. Also a scrappy 4 patch with bright colors works well.

This is one I did as a quickie, it was 6 hours cut to binding. I like it for kids. Did one in red white and blue with red and blue stripes a while back. Also a good starter for beginners.

9 patch furrows is a 9 patch with 3 colors in a specific way

In the one I posted I used orange, a print and green

imagine a square here:

orange, orange, print
orange, print, green
print, green, green

Actually I did a tutorial, if I can dig it up I'll see about posting it later. It's a pretty fast and cute quilt.

I agree with gramajo - I love the Turning Twenty pattern. I've used it for several quilts.

I do 4 patch alternate with a plain block. Sports fabric is appealing to the teen. Plaids work well too.

Thanks for the ideas

I make a lot of baby quilts and appreciate the pattern suggestions you all have sent. Gives me a chance to make something a little different, thanks

I`ve made several log cabin quilts for boys and they seem to love them.

I find the pattern isn't what makes a difference to me. I always try to use bright "happy" colors as my charity quilts go to those who need "comfort" and happiness in their lives.

I've been making quilts for Quilts for Kids. I love the alternating 4 patch with a focus fabric block....then a 1" border followed by a larger border. Simple, quick AND attractive!!
