I like #44, but the hexagons come a little close to a product by a different company in a similar space. If you have any other variations with interlocking/joining pieces, would love to see them!
#45 is really nice too - the # is simple, gives the feel of "threads" for fabric, and the medical cross. Could we maybe get a couple color variations on that one? Thanks!
Would you be able to do #224 with the vertical lines being blue and the horizontal green? If you could also do a font in lowercase that is serif that would be great!
