My motivation and inspiration is the people I care about. I also signed on for the 2014 Quilts for Quilters exchange. That one has a deadline that makes me keep myself working on it. It's also a really fun quilt to me and that helps a lot. My other major priority is a quilt for my grand niece that I want to finish while she's still a baby. After that is a quilt for my wife. That one is giving me fits so I only work on it in between other projects. Coming up is a quilt my daughter and I will make together for her and finally my own that I want to have done before next winter.
It sounds like you have the motivation, it's the inspiration you're looking for. Don't worry, you'll find it again. Sometimes we all need to take a step back and relax a bit. I really need to be in the mood for anything creative like quilting.
Deadlines help, if it was me I'd keep working on the knitting for the June deadline and get started on the cuddle blanket for your niece. She won't be little forever.
Small steps is another excellent strategy. Tell yourself "15 minutes" or "just for a little bit". Some days you may just sit and stare, wondering where to begin, other days you may not look up from your work until 3 hours later and be shocked at what you have accomplished.
Take a deep breath, relax and plan a small part of your day to work on one of your projects.
You'll find your inspiration when the time is right.
