Spring - student project

Just playing - created a spring green background and added the word spring is rose gold metal leaf in a font from my Silhouette Cameo.  My size was very gummy and made an uneven lumpy surface - can I thin it a little or is that counter productive?  Tracing the edges with a fine pen evened out the letters nicely.  There is a splotch where I put size in the wrong place.  oops.
