I sometimes wonder if it is you that is pulling my leg. We have a verbal description of the stains, which is imprecise information. We don't even have measurements of how large the stains were, or how many separate spots, or what the shape of the stains were, etc. All we have is the opinion of those who actually saw the apron piece (which, just to remind you, does not include either you or me), and they indicate the stains looked like they were produced when a knife or hand(s?) was wiped with it.
It is entirely possible for a cloth used that way to primarily be stained on one side, as has been described many times but you ignore the fact that cloth folds. Given fluid will soak through, it is irrational to presume that the other side was pristine, but from the descriptions we have, it appears that those who saw the cloth drew the conclusion that one side was the primary side of the stains, and either the other had minimal direct transfer stains or only showed stains that appeared to be a result of the blood soaking through the cloth.
As far as I'm aware, the idea the cloth was used to carry organs is a relatively recent suggestion. I could be wrong, and maybe there was a contemporary suggestion for that, but I do not ever recall seeing it. Personally, I don't subscribe to that idea because that is not how the stains were described by those who saw it. Also, that use requires one to presume that JtR first goes "home" before going out again to get rid of the apron piece. If, however, he drops it during his departure from Mitre Square, it would make no sense to unwrap the organs while in transit.
And yes, different materials will produce different patterns of staining depending upon the absorbent qualities of the material. The stains produced on a paper towel will look different from stains on a cloth towel which will look different from stains on canvas, even if you place the same item on each. Given we do not know the material the apron was made from, your photos cannot be said to be relevant to the case because the material used is not representative of the material used in 1888 for aprons. Moreover, there are so many other unknowns, that it is impossible to even approach an informative recreation of the situation. And finally, without the original evidence to compare with directly, to examine the resulting staining patterns, there is no possible way to compare your photos with the evidence to determine if what you've produced is or is not similar to anything; you can simply say that you would not describe your pattern the way the stains on the apron piece were described (which simply means you've not done the same thing as was done). See, showing that you can create a different looking pattern of stains isn't informative, because that is always possible by simply not doing what was done. What you have to do is show that it is impossible to create the stains that were on the actual evidence, leading us once again to the problem that we do not have the actual evidence with which to make that comparison.
This isn't difficult or complicated. To compare two things you have to have both things during the comparison. Verbal descriptions of something as complex as a staining pattern are simply too general to make meaningful comparisons to. We are left with the interpretation of those who saw the actual evidence, and they were of the opinion the stains were produced during the cleaning of a knife or hand(s). That opinion might not fit with your theory, and obviously one could be concerned with the accuracy of that opinion given we cannot independently examine the evidence ourselves (same problem), but when it comes to the information we do have to work with it points to the GSG piece having most likely been used to clean up. That probably suggests it was dropped during his flight from Mitre-Square, but it is also reasonable to consider the possibility that JtR first went to some "bolt-hole", and then wanted to discard of the apron piece and so went out again (generally one favours one over the other based upon whether or not they believe PC Long could have missed the apron piece earlier).
