let me try several suggestions..

(I didn't look into function-went just with overall vibe-but function is very important. low traffic,high traffic, easiness of maintenance, how flat and light vs heavy it is, numerous other things..budget of course is important too)

1some soft texture plus pretty allover pattern. reads as pretty neutral because the pattern is more on a subtle side. combines warm tones and a bit of cooler ones

more tribal look-very fitting for a bit rustic nature of saltillo. folks either love it, or they don't. brings in more texture and softness too. has colors of saltillo in it, plus a bit of red you seem to like. and blue(love your owl)) but there are many many tribal rugs..just an example

tribal again-but flatwoven, and more sharp contrast of the pattern. a bit like you have now-stronger geometry..but the look is less contemporary. more traditional, working with saltillo's charater a bit better maybe? still comes off as strong and very self assured. will slide more on saltillo I imagine. unless you use a pad.

very neutral, warmer than it seems on the pic. you bring noot so much of color and pattern, but texture. good to have next to sleeker saltillo.

again, lots of texture. very cozy feel. cleaning might be a pain I imagine. well that depends on a family..would be a pain for me)) but inviting.

my absolute favorite. takes that pink and makes it chic. punchy pattern. born to be a star. luckily (for me because I want it for example) costs an arm and a leg. one needs to fall in love with it and be seriously into florals.

all these -are just vague ideas of directions you could take.

if there's something that speaks to you but we don't know it-let us know..so we can be more helpful

rugs are very personal

I mean everybody can find something that will work, but it's a big surface, and I think -one should love his rug..be sure about it and all.

Nice choices April. If potential dirt is not a problem I like the light colored neutral that looks soft and cozy
