Not at all
Cut it with scissors but it would hurt really bad. Don't try it. See your doctor.
To some extent it will for a second. When stitches are removed there is a little tug of the stitch as it is taken out. You can feel it, but it isn't as bad as when the stitch was put in. I had 8 taken out recently and was glad to have them out since they started to pull a little on the area where they were.
Take tweezers and pull the stitch up as far as possible and then cut as close to the skin as possible
You don't.......that'd why they are self dissolving. They dissolve without being pulled out.
In crochet, the stitches are placed in a continuous stream using the same yarn so they should not pull out at all. If you are concerned about the area when you join new yarn or change colors, the dangling tails should be woven in for a few stitches in one direction, then turn and go back in the other direction. Make sure there is a stitch between so you do not go back into the same spot where you made your first trip. Another way to secure those stitches is to add an edging. Even a plain single crochet edging will present a barrier so the end stitches, which are often chain stitches, are not so easily maneuvered.
It means to add 8 new stitches. You do this by turning needles so they are reversed, then insert right needle into stitches as if to knit, YO (Yarn Over), and pull loop through, slip loop just worked back onto left needle and repeat for required number of stitches. Remember that you do this, casting on of 8 stitches, on the next row also (the "next 2 rows" statement).
Knitting slippers is simple. Cast on 29 stitches. Knit as many rows as you need to fit your foot. Then start knit knit purl purl for as many rows as you need. Cut a tail and pull a plastic needle through the stitches. Take it off the needle along with the stitches and pull tight. Then sew in and out of the slipper. do the same thing with the tail at the end of the slipper.
I would say to the fat tissue at least for stitches. If it is any shallower it can be closed with glue or steri strips.
Stitches
ssk = slip slip knit That means you slip the next two stitches, individually, knit-wise (insert right needle under stitch and remove) back to the right needle. Then insert the left needle underneath the slipped stitches, wrap yarn around the back of the right needle, then pull the yarn through the slipped stitches from the back, take worked stitches off left needle.
back stitches, machine . running stitches
If you are having a problem with your work pulling in, you might need to work a bit looser. Pull up on your hook as you work your stitches so the yarn and stitch come up to the height of the rest of the stitches.
