I'll echo what Lisa said
@elseepe , I love how you have lots of "generic" items in your kits so they can be used for a huge variety of layout topics! I LOVE your string bits and the little word bits you add too.
I'd love to see a DIY type of kit from you. I'm constantly fixing things or building things around the house and I'd love a kit to capture those type of projects. I don't need a hammer, saw and drill type element in there, but rather things like screw heads, little nails, maybe some bits of saw dust, a brush with the ruler markings, etc. Then papers with wood grains and maybe with and without paint splatters? Then of course your awesome word strips too.
I'd also love a kit about cleaning and/or organizing that isn't super cutesy. We've been doing tons of purging in our house, going through closets and drawers and shelves and getting rid of things (donating, giving away on FB, etc). So fun word bits related to that would be great too. (purging, organizing, "do I really need this?", "what is this?", "donate pile", giveaway, onto the next owner, gross, so dirty!, "Do animals live in here?")
and finally, I know that most of us capture the happiest moments in our scrapbooks, but sometimes I need to make a ranting page or capture something not so great that's happened in our life, so I'd love a kit to use to document the "hard" moments of life. elements like question marks and exclamation points. sketched mad faces or shocked faces. Angry scribbles, etc. wadded up paper, torn paper bits. word bits about frustration, exhaustion, confusion, uncertaintly, etc.
not sure if you're still looking for inspiration, but I am really missing kits and stuff for us nerds think computers, programming, gaming (both boardgames and pc games),card collecting etc.
We don't know if it's a girl or boy, but I'm hoping you'll consider adding some new baby and toddler type kits to your product line. I still haven't scrapped all of Maddyn and Weston's newborn photos and would love to have some kits to pull from for both girls and boys! Nothing too cutesy, just in your signature style. Think welcoming baby home, big sister, big brother, little one, sweet dreams, shhh... baby sleeping, nursery rhymes, etc.
