That is one of the things I LOVE LOVE LOVE about Missouri Star Quilt! Any precuts they have posted on the site, they have an adjoining link that shows the ENTIRE collection in that precut selection. Sometimes, I've seen charms or layer cakes for sale that show a multicolor print as the top square, but when I've looked at the whole selection, I didn't care for several other prints in the collection. Not all shops show it that way, as far as I've seen Missouri Star Quilt always does. It does help to have several shops & sites that you are familiar with & know how they show what they sell and also how friendly their customer service is.
I have that same set of charms but also got the panel for it from a different shop, so that I could use them together. You might also find some jelly strips that would coordinate or pull them together. If it was a good deal, I'd find a way to use them.
