My cost for all of this so far? $1.29, the price of a new package of 1/4 inch elastic. I used fabric from my stash to make the gowns, plus the YCMT "Portrait Peasant" pattern I already own. Not bad for a gift that I am certain they will love.
Next up after the dresses is the Reversible Crayon Apron. I'm tentatively planning to mix stash and new fabrics for this one, as my collection of colorful calico has been depleted by my oldest daughter. I'm proud to say that she's learning to sew, too!
