My oldest daughter wore the gown I was blessed in for her baby blessing, and I plan to hand it down to her for her own children. For my younger daughter I made her a gown so she'll have something to hand down to her own children if she would like to.
Here's my baby girl wearing the blessing gown I made her. Unfortunately at the time of the photo she wasn't exactly happy...
The body fabric is cotton knit, and the ruffles are white and off-white satin and polyester lace.
I used this pattern from Sew Much Ado (I purchased the full pattern because I like it so much) and this tutorial for a ruffle dress from Kojo Designs and meshed the two together to make my daughter's blessing gown. I don't like unfinished edges, so I used my serger to make rolled hems on the edges of the satin ruffles, and I used this tutorial for gathering on a Brother serger to make the ruffling go so much faster. I also used this tutorial on Make It & Love It to make the flower on her headband out of left over lace.
