I haven't studied any recipes on making creamed honey---I sort of came to it by luck.
A few short comments:
1. I would never heat up the honey in preparation for creaming. That could melt the seed crystals and eliminate them entirely.
2. I've never used seed honey from any other source than my own crystalllized honey.
3. Whipping the honey serves the purpose of physically breaking down large crystals into smaller ones ("seed" size) and spreading them evenly throughout the honey.
4. IMHO, the mixing process is the key to a successful start. The next important step is the cooling of the mixture (honey + small crystals) quickly. Rapid crystallization (encouraged by cooling) speeds crystallization and prevents the creation of large crystals thus giving you a nice smooth texture.
Since you use your paint mixer, you might try to add a little color to your cream
But really----it just dawned on me, you could try using a minute amount of food coloring, prepare holiday colored batches and market them in layers inside your jars. It might be a dud but if done nicely, it could be a holiday hit.
