A while back, during my last machine quilting class, I promised to post information about a very interesting online resource for machine quilters. So, here it is. The Website is daystyledesigns.com and is the work of Leah Day. I'm sure you'll be amazed at her output of ideas for machine quilters.
If you find it a bit overwhelming, remember that practice is important. Take some fabrics you're tired of or buy some just for the purpose of practicing, it doesn't have to be the 'good' stuff, this a good time to use up the uglies in your stash. You'll have more control of the patterns if you can see what you're doing so try putting a solid or near solid fabric on the working side and a print on the backside. You'll be able to see what you're doing on the solid and then how the pattern looks on the printed backside. Be ready to go in advance so you don't have any excuses. Assemble some practice fabric snadwiches or just some felt (2 layers) and give yourself permission to just play.
