I thought you might enjoy seeing the quilts I've donated in past years, as they have all been simple ones that have been fun yet non-stressful to sew together. I've linked each quilt name to the pattern or tutorial for easy reference.
Comic Strip (2011)
pattern and Sherbet Pips fabric by Aneela/comfortstitching
tutorial by Rae/made by RAE
Sweet Baby Girlie Charm Square Quilt (2012)
tutorial by Elizabeth/Don't Call Me Betsy
Star Bright tutorial by Katie/Swim Bike Quilt
And while I'm hoping to make another donation quilt by the end of September, so far I have 2¢ Stamp all ready to go.
If you're interested in joining in, Heather posted a few ideas recently and has a Charity Quilt Inspiration board full of them. There's also the #100quilts4kids hashtag on Instagram and the finished quilt link up itself - plenty of inspiration to create a special quilt to share.
