Another bumpie posted a link to a recipe for this. I didn't bookmark it, but found a similar recipe here:
https://www.theimaginationtree.com/2010/10/salt-dough-handprints.html
I tried it this morning and have a couple tips if you're interested in trying it too..
The dough gets a bit sticky the more you work with it, add more flour if your rolling pin starts sticking to it.
Roll directly on to parchment paper that is cut to fit on your baking sheet, moving the dough at all is impossible to do without marring it once it's been rolled out.
Roll the dough to slightly more than a1/4 inch, otherwise it'll be too thin when you make the print.
I used a teacup like a cookie cutter to get perfect circles just big enough for lo's hands and feet.
Cut out more discs than you need so you can chose the best prints or in case you flub one or two.
I found that one recipe made about 4 teacup sized discs and two smaller ones that I'll use as labels. I got two hand and foot prints, I'm going to write Hank's name and age on the labels and then mount one of each into shadow box for us and for my parents.
They're in the oven now, but I'll try to post a pic once it's done.
Re: Salt dough hand/foot prints
If you mess up, you can just reroll this dough!
Yep this! Evan curled his toes in a couple of times, so I had to reroll it. Also, if you want to hang it, just use a straw to create a hole at the top after you roll it out.
