just my own experience here…..
i often go with more rounded fonts with small text, well, i avoid any small stuff where poss if i can !! something like ariel rounded, cooper somethingorother, and a couple of others, just try an avoid corners,
always cut spares, if you need 20 stickers, but can cut an additional 5 in what would normally be wasted space, then do so and have them as spares.
make sure to put cut lines in between lines so as to only weed one line of text at a time.
recently on small stickers, someone said to weed it fast, get the edge up and rip it off, "yeah right" thinks I, well after spending an hour weeding 15 carbon vinyl stickers, i decided that since i had three spares, i would try doing one fast on one of the three, result ? not one lost letter, dot, or otherwise, 15 remaining stickers done in as many minutes !
to do the above, the cut must be just right though, do a test cut and check to see if any particular letters ‘catch’ or don’t cut properly, once identified, you could convert to curves and edit the nodes to sort it out, not all fonts are perfect !
the other thing i always to, it weed the waste from the end of the sentence to the beginning, and numbers from the beginning to end, this minimises the amount of bits that weed less easy, such as ‘c’, ‘e’ ‘k’ etc, does that make sense ?
hope some of that is of use !
