I love this quilt block, because you can have so much fun with it playing with ribbons and trims for decoration.   It is also a very easy quilt block to make.

There are a couple of ways to approach making this quilt block.  If you want to make it with trims and laces, the center of the block is made like a  Snowball Quilt Block. Then you sew you embellishments on top of the block.  You do not have to worry about the edge of the trim, because it will be caught up in the seam allowance when you add the border to the block.

If you want to use all fabric to make the bulb, you can either seam the pieces in the picture together, or you can make the basic bulb and topstitch the additional fabric down the center. 

If you want to seam the fabric, work in rows.  Your first row uses the snowball technique on both sides of the rectangle to shape the side. The bottom row of the bulb is constructed the same way.

Cut a rectangle for the center of the bulb out of a different fabric, and some very thin rectangles to attach to each side of it.  Then stitch this piece to the top and bottom row.

Finally, cut 2 side borders to match the bulb section per the picture, a strip for the bottom, and make the top row using 2 wide rectangles and a narrow on for the stem.

Here is a visual of this block with a few other quilt blocks:
