In the the second (and last) part of the little bouquet I'll share how I completed this piece.
It is my contribution to Work in Progress Wednesday, hosted by SharonB
Anna Scott wrote a clear tutorial about lacing.
From firm cardboard I cut an oval piece and overlaid it with batting.
Along the edge of the embroidered piece I basted with a double thread.
I basted in two parts, one in the top half and one in the lower half. I thought it would be easier that way to pull the thread to gather the fabric around the cardboard.
On the picture from bottom to top: the basted embroidered front, an extra layer of batting and the cardboard.
The two gathering threads are pulled around the cardboard and fastened.
The fabric is stretched around the cardboard.
From the same fabric I sewed a layer at the backside. A ribbon loop is sewed in between.
The finished bouquet.
