I made these sandwiches myself - I didn't buy them, I MADE them! (I've put it in the past simple as it seems more natural - unless you really want to use the present simple and make a statement about a regular habit). I made these sandwiches ON MY OWN - suggests you made them yourself and WITHOUT ANY HELP from others. It could be you were alone, or you had company but nobody aided you. It rather depends on your TONE OF VOICE. Children, for instance, proud of their achievements, might say, "I made these MYSELF!" (without help from mum). It would carry the same meaning as, "I made them ON MY OWN!" (without help from mum). So, although "ON MY OWN" can carry that extra emphasis of being alone, they can also be used interchangeably. So be careful, and look at the context. For example: "There was nobody to help. I had to do it MYSELF!" carries as much meaning as, "I had to do it ON MY OWN!" However, "I made them myself!" is probably just a statement that you didn't buy them or get somebody else to make them, whereas "I made them ON MY OWN!" could be a COMPLAINT that nobody helped. Mind you, "I made them MYSELF!!!" could ALSO be a complaint that nobody helped! Practice the intonation!

Saying "I make these sandwiches myself" means they are home-made, not bought in the supermarket. If you say "I make these sandwiches on my own" it means you don't have any help to make them. In my opinion there is a subtle difference.

Those are both valid sentences but they have slightly different meanings. Though most native speakers would probably not separate them, or they may find "on my own" to sound more like a child. Importantly these sentences imply that making sandwiches is something that you engage in but does not provide a time reference. This is similar to saying "I play tennis". "I make these sandwiches on my own." - Focuses on the fact that you make the sandwiches without other people. Almost as If you were proud of this fact. "I make these sandwiches myself." - Focuses more on the fact that the sandwiches are made by you as opposed to by someone else. One commenter said that ' "I made these sandwiches on my own" or "I made these sandwiches" ' is correct. these sentences while correct English are different than the sentences that you wrote. You would use these versions to imply that the sandwich making happened in the past. Similar to answering the question "what did you do this morning?" with "I played tennis". "I made these sandwiches myself" is also correct English. I should also say these sentences have the same difference in meaning as I described above but with the different time focus. in addition, "I made these sandwiches" does not imply that you made the sandwiches by yourself. With that version it is possible that you had help. edit: In the context of your journal entry "...myself" is correct and "...on my own" is not. In your story the man was describing how he made the sandwiches as opposed to his wife. The fact that he makes them on his own may be true but is irrelevant to the point he was trying to make. Hope this helps!!!

Both of those endings are fine, it's just a matter of preference. The beginning should be modified though. It would either be, "I made these sandwiches on my own" or "I'm making these sandwiches on my own" (or "myself"). If it's supposed to be future tense, then it would be "I will make these sandwiches myself" or "on my own." It should be noted though that if you're accusing someone of not helping you to make the sandwiches, "on my own" sounds a little stronger.

The correct thing to say would be "I made these sandwiches on my own" or "I made these sandwhiches"
