Ok I know I'm doing something illegal, posting twice in a row but it just might be worth it. So I was thinking, if I was a knitted alligator bump and was really lazy, how would I have come in to existense? The simple answer was by ktfbl and k2tog!!!! To try out my theory i co 6 stitches, 2 on each edge and two inbetween my two alligator bumps. So eager to try out my theory I did this
row 1: k1 ktfbl k1 ktfbl k2
2: knit all (same all even rows)
3: k2 ktfbl k2 ktfbl k2
5: k2 ktfbl (2 times) k2 ktfbl (2 times) k2
7: k2 ktfbl (4times) k2 ktfbl (4 times) k2
9: k2 k2tog (4 times) k2 k2tog (4 times) k2
11: k2 k2tog (2 times) k2 k2tog (2 times) k2
13:k2 k2tog k2tog k2
Now when pushing on the sides slightly I see triangular bumps appear!!!
Well mine look kinda sloppy, mostly cuz it was some scarp yarn on the wrong needles and done in a hurry... but the method should work.
To make it look better I would work in the round, only putting bumps on half, using that as the front and using the un-bumped side as the back. Also it might be a good idea to block the piece to make it maintain its shape.
