She may just need to find friends who like to play the way she does. Some kids love to be more directed and do crafts, play specific games, etc. Others would rather disappear and start pretending together. I'm not sure what you mean when you say these other kids seem "bored" with your child when they get together. Think through the specifics of what you have observed -- Did the other child leave your daughter and start to wander the house as if looking for something to do? Did you find your daughter sitting reading during the play date while her friend sat separately doing nothing? Figure out the specifics. It sounds as if you might need to talk gently with your child and remind her that when a friend's over, she might not want to start drawiing or journaling unless she somehow involves that friend -- a lot of my daughter's friends love doing secret codes together in journals they both can share, for instance.
Before a play date, ask your daughter: Would you like to go to the craft store and get something for you and X to try? Let her pick out more than one craft kit in case the other kid isn't into making bracelets but would love making "perfumes" from distilled water and essential oils. Girls this age often love crafts so your child can have fun coming up with themed things to do -- making spa stuff (perfumes, body scrubs from sugar and essential oils, eye pillows from new socks stuffed with dry rice and lavender -- there are lots of ideas online). Or jewelry making, or playing outdoors with all her toys out so they both can choose. Or take the girls for a specific activity like (depending on the season) mini-golf, bowling or even the good old playground. Sometimes having an activity planned can help break the ice and the next time the kids may be more apt to come up with something on their own. But be sure your daughter, not you, does most of that planning, so you are not her social secretary but her helper and provider of supplies.
Over time your girl will have friends with whom she vanishes and has tons of fun in her room or the yard, but give her time. Meanwhile, look into Girl Scouts, school clubs, church groups if that's your thing, or other outlets to meet girls her age. And it's OK if overall she is happy doing things on her own -- that is actually a great skill to have.
One last thing; someone said that at this age they move from playdates to sleepovers. I don't find that true at all. Sleepovers require more work and from what other moms tell me, sleepovers just as "playdates" can last so long that girls get tired of each other and bored and can get a bit testy with each other, depending on the personalities involved. I reserve sleepovers only for birthday parties. There are plenty of playdates to have that aren't sleepovers.
