Wonderful! Must have one. But not pink... I'm thinking cream or purple. Ooh or silver or emerald or sapphire... Is it too weird to ask if you could email me any extra photos you have? I would put them up on this thread for you as well if you wanted. How much fabric did you need? I wonder if I could get away with not putting legs on it...
Your best option is probably to sew a line of stitches beside your cutting line: let's say you had a square of knitting and you wanted it to be circular. You could sew a circle of stitches in the fabric (outline of a circle) and cut around it (on the outside). The fabric outside the circle would fall apart. The circle would be intact. The stitches must be capable of holding the yarn stitches together though so fairly small and tight.
I've known of completely blind knitters. I imagine that certain types of projects would be difficult or unachieveable for them (e.g. very fine lace). But many people knit without looking. If you are just thinking about teaching yourself to knit without looking, it won't be immediate. Try knitting garter stitch in front of the TV to start with, or knitting one stitch without looking, then try two without looking, then four... then try it in front of the TV. Depending on the extent of your (potential future) loss of vision, you may be able to do different types of projects, but it won't be impossible. However even if you are a very good knitter now, it may not necessarily folow that you will be automatically capable of doing it without looking. For the next month or two, try looking at your knitting less and less, I think you will notice a difference.
I can't think of any latex-type gloves that would be 'breathable' as I understand you. If I were to wear gloves while knitting because the feel of some fibres bothered me, I would try very fine cotton gloves. Or perhaps you might find your hands felt different if you used a moisturiser - maybe one from the chemist that is a lotion good for irritation etc. - or if you find that you dislike the feel of rayon after say 90 minutes, you could have another project going in another fibre and only do an hour per day max. on the rayon project? Talcum powder on the hands might also make it feel better (depending on the exact nature of the yucky feeling you get with rayon).
Many people hate working with cotton and even find it uncomfortable/painful. If you can't find a fix that allows you to work with uncomfortable fibres comfortably (if you know what I mean) maybe try slowly graduating away? Like if you hate cotton, how do you feel about 50% cotton and 50% something else? 60% cotton? 80% cotton?
Cotton and rayon have some nice properties - if you want to knit with those for example, perhaps it's because you don't like animal fibres (your tactile dislike of cotton and rayon aside)? If that were the case you might like to check out bamboo, corn/maize, soy etc. fibres? Silk?
Have a look at Knitty, a link on weaving in ends with duplicate stitch - there's a useful diagram with hand-drawn lines showing you what's going on. I am quite lazy and often weave in ends on garter stitch the same way I would on the purl side of stocking stitch - also it doesn't go through to the front.
I agree that it would not do well in the microwave but on top of that, even if it didn't catch fire or melt, it would easily get too hot, because the melting/burning point would be high. That's why oil burns you so bad - apart from the fact that it sticks to the skin, it heats up to MUCH hotter than water does, so it burns you more. I think that e.g. wool or cotton (while both flammable) will not heat to the point where they will burn you badly. Also there might be potential for toxic fumes to be released and you might not even know you were breathing them.
Depends on the weather, how many layers will the bub be wearing underneath? Looking at commercial baby clothes for the size you want might help (for ease, compare outer garments like other jumpers rather than cotton singlets). One or two inches sounds about right, if not sure make it a touch bigger so the bub will grow into it, if too small it will never fit.
