Mandy from It Will Change Your Life, made a potted 'plant' of grandchildren flowers. That's 20 grandkids. I think this is easy enough to make without instructions.
Samantha from Simply Organized has a great idea any mom would love, Handprint Art. Since kids grow so fast, it's great to have a remember when? I love it. She offers a tutorial on her site.
Kelli and Kristi from Lolly Jane Boutique, offers another great way to keep the memories of your kids small hands alive. They have a tutorial on their site, too.
There are more ideas available if you need them. Have a fun day.
