I need to purchase molds to make fondant pearls for a wedding cake, wondered if anyone can suggest a good brand,

First Impressions brand, Perfect Pearls 6, 8, 10 mm Mold:  http://www.globalsugarart.com/perfect-pearls-10-mm-mold-by-first-impressions-molds-p-21438.html?gclid=CjwKEAjwru6oBRDDp4jRj4bL_xASJADJ2obyYgKAii_VNGDmgYrUQLrXf8h2U9itK2Er7KPmrQqiaRoCIyHw_wcB&gdftrk=gdfV25706_a_7c2149_a_7c8856_a_7c21438

The mold listed above may be the ideal mold for your needs.  Since this is your first pearl mold purchase, be aware that these come in many different sizes, lengths, and some are even oblong (not round).  It is very hard to tell when ordering online unless you really read the description.
