Because each of us is an egg, a unique soul enclosed in a fragile egg. Haruki Murakami
So, it doesn't surprise me that on my first attempt, I made my rabbit a bit too big for the egg but I was still very happy with how it turned out at the time. I found a photo-tutorial here that helped a lot! I was able to create the bunny egg above and the chick egg below by studying this tutorial.
You can find a video review of how I created the chick egg pictured below on my YouTube channel. The episode was titled Easter Needle Felting (2018). Click here to view it.
There is a video on YouTube that got me started with needle felting a solid Faux Fabergé egg. You can find it here. Below is a photo of my initial attempt. I'll admit, the new skills I acquired were more impressive than the final product. But, I think the learning experience was well worth the effort. Needle felting the egg shape itself is taught as a beginner's project in the video: there are lots of explanations and tips to help you. However, the actual egg decoration was done off screen. I'm sure I could have made a more attractive piece if we (the video host and I) had not been in such a hurry to complete the video. The host does show other completed eggs that give you an idea of additional possibilities.
