Hi Amanda... I just saw this... how is your doll coming along? I have made quite a few in the last year!
Want to recommend a book that has great tips, patterns (for dolls and clothes) Making Waldorf Dolls by Maricristin Sealy It is the BEST book I've seen on doll making (and I checked out everyone I could find from the library!). It is spendy but worth every penny.
Here are my extra tips gained from experiance and from other people's recommendations:
Use a chopstick for doing arms and legs and for stuffing- for arms and legs make small tight balls of wool for feet and hands and stuff thumb, then roll the wool around the chopstick in a length that is needed for the arm, then slide it in like a sock- this makes for a hard tight foot/hand and then a smooth arm (try and stuff inside the "tube" you made if you need extra stuffing- hard, but possible)
Not sure if you purchased craft thread for tying head, but waxed dental floss works really well, and since it is waxed it helps keep your knots from slipping a bit better than craft thread, and its easy to find and cheap
Things that she recommended that my other kit patterns didn't was to use a zig zag stretch stitch when sewing the body. Totally helps keep seams from popping when you stuff.
Also I sew BEFORE I cut pieces out then cut to my seam allowance, this helps keep the machine from "eating" the knit edges. Also be sure to use the ball point needle and depending on how your machine sews, you may need to slightly stretch the fabric when sewing across the grain to avoid skipped stitches. If you do get "holes" or skipped stitches, you can just sew over them again with the machine or hand sew them.
I also use a vanishing marker to trace my patterns and for marking my eye/mouth placement- I use pins to mark the eye and mouth first then remove them and draw the size/shape eyes/mouth I want to make- helps me make them even and straight.
When sewing eyes/mouth, I use the doll makers needle to go in from the front, (no knot in the thread) remove doll needle, tie a knot at the back of the head, then use a smaller needle to stitch features for eyes, then re-attach doll needle to get "tail" to back of head on last stitch. For the mouth, go in your first hole from the front, then tie in back, rethread doll needle in front stitch to back of head- if you want a double stitch mouth, then use doll needle to come back to front and then back to back of head.
Get a good thimble and be sure to "catch wool" when attaching the head and hair- if you just sew in the fabric you can risk the "skin" getting a run in it. This means you have to push HARD sometimes to get it through, which makes for sore fingers. Thimbles help a ton.
Hope this helps and let me know if you have any questions - you may be done by now, but figured I'd give you my 2 cents in case you haven't
