  "description": "I was having problems with an almost finished Persona.. I was tired of struggling with it. Rats-I really wanted to upload Something...Oh, a brilliant idea! What about a SOLIDS Persona? That would be quick & easy, right? Ha.. I tried & rejected color after color. I really wanted  multiple hues--& a pattern! I finally made this striped violety blue one.When I put it on my browser it didn't look solid at all.  How in the world do you Solid Making Designers DO it? My hat's off to you... c0l1\n\n\nAn original Abstract design by CollieSmile."
