Puffy, quilted shapes

Go to Google Images, type in "Quilts" and you will get many hits.

In PSE Editor, Expert tab, open a quilt pattern

Go to Filter menu>Distort>Liquify and you have many options, e.g. Turbulance, Pucker, Distort, etc.

Love your handle that's precious.  I think your best bet is to search custom shapes catalogs on the internet and make a purchase of any you find useful.  Alternately, if you're familiar with "Clip Art" you may find taking that route as useful for your marketing needs though a smidge more challenging to incorporate compared to shapes.  But creating shapes yourself require's different software and another learning curve.  I don't know of a way to make existing shapes in PSE look puffier.  You basically only have control over height, width and rotation, either filled or not filled.
