Thanks! I’ll do my best to answer your questions.
1) For the feet, only the felt bottoms of the feet were glued on via contact cement around the edges and toes. There is an oval cardboard or styrene insert where I put some stuffing on top of to give his feet that subtle bulge on the tops of his feet. Here’s an old drawing I made hopefully show how I did this. Basically, the foot is constructed first. To make it easier, I cut out the foot shape from the fleece first, then I glue the oval insert to a piece of felt (for the bottoms of the feet). I then slowly use contact cement to glue the edges of the felt to the fleece foot cutout (no need to trim the felt to a foot shape yet until it’s glued onto the fleece; much easier that way). Before I completely glue on the felt bottom all the way around the foot, I will add a small bit of stuffing that sits in between the felt and fleece, and on top of the insert. This will give the foot that little bulge that can be seen on top. Once that’s in, I just simply use contact cement to glue the felt all the way on the fleece—toes, etc. After that, you can just take a pair of sharp scissors and trim the felt, using the outline of the already cut fleece foot as a guide. I then sew the foot onto the leg; this is a bit awkward, but to aid the process, I make sure the leg is already stuffed so that it forms a cylinder shape. Since it’s hard to use pins for this, I just slowly sew the bottom of the leg to the foot. It’s not too bad after some practice.

2) For the arms/legs, there is only stitching running along one edge, so just basically just use the pattern as is, but fold it in half so the edges meet and sew along there. Kermit’s limbs are quite noodle thin on the original puppet I saw—especially his arms. The new patterns I use for my arms look something like seen below—basically the palms and thumbs are all one piece, which is more effective that what I did on my older builds.

3) The arms and legs are just sewn onto the body using the same “Henson” stitch—aka ladder stitch. It’s a bit awkward at first, but for the arms, you can just use pins to pin them onto the body first and then sew as usual. For the legs, as mentioned earlier, I’d recommend putting in the stuffing or foam in them first, so that they are more cylinder-like, making it easier to sew them onto the feet.

Kind of difficult to show how the stitching looks on the final, as the seams really do hide very well. For the shoulder where the arm meets the body, just make sure there isn’t any stuffing around that area—this creates that flattened shoulder joint
look that you can easily see on the originals. If there’s stuffing or foam there, his arms would not sit right.

Hope this helps!
