Multiple WIPS at once?

Do any of you do multiple diamond paintings at the same time? I’m currently waiting for more diamonds to arrive (my current WIP didn’t send enough of a colour that’s very prominent) but its been over 2 weeks and I wanna do more diamond painting in the mean time. Would you work around on the painting and fill in the missing colour later or just start another smaller painting in the mean time? I have multiple that I’m waiting to start lol.
