Well, I tried something different this evening. The home sewing market is being flooded with many quick and easy patterns. There are many that take advantage of "the fat quarter", mixing & matching coordinating fabrics and so forth. Though in the end, I wasn't happy with my fabric selections or the way they photographed, the pattern was relatively painless. There isn't much "fit" to the pattern for the child that would wear it, but it probably would be a comfortable dress.
Poppy's Easy Dress is by Vanilla House Patterns. It is a kimono style dress. It boasts of no set in sleeves, zippers, plackets, buttonhole or fitting issues. My only "issue" with the pattern was the addition of rick-rack to the bodice seam in the front and back. The pattern says to add the trim before the side seams are stitched. However when you do that you have a bit of trouble with the underarm seam. So I would recommend adding the trim at the very end. I would also make the suggestion that in choosing your fabrics, choose ones that have a common background color. Though most of my fabrics had white, I did choose a couple of solid fabrics that when you are machine stitching the hem, the white thread stands out.
The dress did go together in a couple of hours except for my rick-rack issue. It is quick and easy. It doesn't take a lot of fabric either. Give it a try!
