I don't want Sarah to feel like she's the only one here that says there are still some happy customers but none of them are posting so I'd just like to comment that I did have a project with Liz recently and I think it went rather smoothly and was very happy with the result.
Also, I'm glad that people were willing to post about their experience honestly even if it was a bad one and I did read this thread before I started the project so I knew what I was getting into.
Overall, I think the thread was very informative and it helped me with the whole custom design process, what to expect and important things to note even before the project starts. Basically all the ground work had to be done and listed so that there were no assumptions on my part. With all that aside, I had no troubles at all and even though none of the network jewelers would work on her pieces, that wasn't an issue for me since I wouldn't have mailed the ring for resizing back to Liz herself, let alone another jeweler.
Overall, I think the price I paid for a custom made ring and the quality of that ring was well worth it but most importantly, within budget!
