Any Solution To This Problem

I accidentally ordered the wrong type of beads, Toho Round 11's instead of cylinder 11's.  I warped the loom for my project and the first row of strung  beads was wavy and then I realized the beads I was using were too large for the warps/spring I was using.  Re-warped using ever other dent.  I now have the project complete but it is apparent there is too much space between the beads so they do not lie flush next to one another.  Am thinking of using a slightly larger weft thread and going through all the rows to tighten, or do I need to re-warp and start all over using a different spring?
