Ahh, the petaled shoulder top - this is one of my favorites and it's easy to boot! The very first step to this tutorial is to create a basic tank (1st part of this post - directions here). I used a navy polyester from Joann's that was labeled as "Baby Silk" and indeed it does feel very silky. It has more of a matte finish so it doesn't look 1970s polyester which is also a plus.
Another retroactive tutorial after the jump...
Once you've created your tank, you're ready to cut and assemble your petals. The beauty of this top is that you have all kinds of creative freedom in terms of size and shape of your petals, but I will just show you what I did for this particular top.
First, cut your petals. I used 5 petals for each side and you'll need 2 flaps per petal for a grand total of 20 flaps. I cut various shapes - mostly with one lobe and then a petal with two lobes (kind of looks like a butt). Each shape = 4 flaps of fabric because I wanted the shoulders to be symmetrical.
Once you have 4 flaps of each shape, pair up the flaps of each shape with the "wrong" side of the fabric on the outsides. Sew the flaps together (except for the flat top portion) and then flip inside out. You should now have your petals.
See those triangles in the illustration above? That's where you'll pleat your petals and sew up the top.
The first petal for attachment is the two-lobed one and you will just sew a straight line on the inside shoulder of the top (nearest your neck).
Next arrange the 2 smaller petals under the two-lobed petal and stitch it to the shoulder. You can see where my stitches are in the picture above this one.
Do the same thing for the bottom 2 petals.
Now repeat for the other shoulder and voila! Petaled shoulder top!
