I'm not sure why I'm just now seeing this. Good idea.
It's been a few years for me since I was doing trauma work, but I recall how helpful it was for me to have a 'self care kit' assembled. I put one together when I was in an okay headspace and had it ready for times I was not. It was full of things that soothed me. I kept that thing by this comfy chair I'd curl up in when things got especially rough so it required no thought to find it. It was always there. I had issues with this things like body memories, flashbacks, and getting holed up in my head in the worst kinds of ways. The self care kit had things in it that I would use as an anchor to reality, so to speak. I remember stumbling onto citrus fruit as a nice way to engage multiple senses at once and it really helped to keep me present and give me something to focus on outside of myself. I could roll an orange, for example, around in my hands, maybe toss it back and forth from hand to hand, see it, smell it, and it was really helpful to me. Sounds silly, but I swear, oranges and the like were a must have for me for a while there. I found them awesome anchors when one is needed and totally worth keeping in a self care kit.
