I recently embarked on trying my hand at a plate with straight stringers all lined up. I am not sure I have the perfect magic recipe, but here is what worked for me.
My first attempt was to take my stringers, lay them all next to each other on top of a clear base. I was afraid that as they fused and spread, they would not stay straight, so I put a dam on the outside edges.
In general, it wasn’t a bad attempt as most of them were straight, but since I had dammed it, I think as it spread it pushed some of the stringers up and so you can see about 1/3 from the top a purple one that is slightly higher and spread more than the others.
My second attempt was to first tack fuse the stringers to a sheet of clear. The clear lines were also clear stringers. And the tack fuse, I then took them to a full fuse. I was hoping by tack fusing them that when they then fully fused they would stay straight. Was I wrong! This was the worst one as you can see in the picture. Lots of wavy lines.
Now on to my third attempt. For this one, instead of completely covering the clear sheet with stringers using clear stringers between the colored ones, I decided to just fuse the colored stringers to the clear base and have the base itself be the clear stringers. So using a ruler, I carefully laid out the stringers keeping them equidistant apart and then did a full fuse. This worked the best of all.
So what did I do with my good pieceof straight stringers? I put it between colors that matched the stripes! A nice final piece to show for my testing.
