If I'm picking on you its usually because I think you have excellent talent and or ingenuity. In your case, I see a bit of both. You've got some excellent healing showing on many of your grafts which shows me that either you A.... used parafilm B... had excellent humidity... or C... a little of both. With that being said, parafilm is not without its faults. No method is perfect, but you have done well with the grafts I've seen and that tells me you listen to what your grafts are telling you. I.e. you pay attention to whats going on. Two thumbs up @Gimli.

Very good work here. You appear to have listened to your grafts well as they stock has healed up very nicely. That first one is especially nice. Now to hurry up and wait for it to do something for us. jourdaniana varietal mam ...

I've gotten a few monster specimens off of this cross as well. Some of which I have already dispersed on ebay and the like... unnamed. Those specimens may never be named as they circulate and as such.... many may find themselves getting two or three of the same exact cultivar thinking they are getting something different. To name or not to name... that is always the question, but once done I believe it is an excellent way of keeping track of a specimen and ensuring one does not buy duplicates of the same. Excellent specimen by the way!

Yeah, chemicals can be hazardous if improperly handled. Even household bleach can kill. Bottom line, don't sniff, drink, or otherwise touch chemicals with your bare hands if you haven't read the SDS or MSDS on them and are sure that it is okay. . If your not willing to read an SDS or MSDS or take simple precautions such as wearing gloves to protect yourself from some of the more hazardous chemicals you probably shouldn't be allowed around chemicals.

These girls no how to handle their bagpipes...

This one is just bursting out of its parafilm hymen and already nice and cherry red for @bardo and @Gimli. Thought the two of you might appreciate this one.

Examples of how long I leave my parafilm on... Here you can see I forgot to remove the parafilm altogether Aesthetically speaking... removing the parfilm in a three weeks from this stage would be perfect for me

Not all Lophophora are able to self-pollinate. Take this little one here for example... It and others in its geographic location are known not to self-pollinate. If one concludes that self-fertilization results in decreased fertility and lowered seed set as is often the case from the sources I have read on and that the result of outcrossing is often an increased seed set... perhaps it is simply the fact that you are rolling the dice with the same sets of chromosomes and albeit they may be more mixed up... the sets themselves have not changed as much as rolling the dice with an unrelated individual. For what its worth, crossing a Brugmansia aurea or such back to its mother repeatedly also lowers the fertility rate and eventually results in a Brugmansia that rarely if ever sets seeds to its parent if this is done for approximately 3-4 generations. Big BendHuizache La Paloma pollens all vary greatly from one another, yet they are all the same species. Then you get into some of the hybrids and the pollen changes again.

Thought I would show a few more seeds busting through the parafilm and one seedling that the parafilm was never removed from...Besides the parafilm looking like it spent too much time in an ashtray, everything goes just fine this way.

Definitely depends on what your growing and where. For instance... if one was mass sowing pejuta along the Texas border... the cacti is already indigenous there so no real harm.

Parafilm splitting... this is how seedlings penetrate

48 days old... and a nice hybrid cousin

If you dig deep enough, you will likely find I have Datura pistils grafted onto Brugmansia and vice versa. My suggestion to you... try everything you desire. It is the only way you can prove to yourself what works and what doesn't. I know sometimes crosses that are taught to produce one result.... when one actually does them... much different results are sometimes found. Whether that is because the "expert" tried and failed or because the "expert" was going on prior knowledge... who knows. What I can tell you is that no two seedlings are alike and no two grafters are alike. What works for you... may not work so well for me because perhaps you have a better box cutter blade or some other technique that I have not discovered yet and vice versa. When you have extra of something... that is when the fun begins. Graft both ways and see what works best for you. Graft to versicolor stock, suaveolens stock, aurea stock, hybrids, etc. Go wild with it. See if anything new pops up for you. Perhaps you are more observant and will note things that the previous grafter did not notice when it comes to the influence of the stock on the scion. There are many reasons to graft, but my favorite reason to graft is simply because its fun and can give unexpected results sometimes such as those rare chimera plants one sees every so often. Now, can you imagine a cold x warm group chimera.....
