How to store an unfinished diamond painting kit between sessions
A kit is easier to pick up again if you can find the next symbol before you open a bag. Here is a pack-away routine for a shared dining table.

Return loose gems to a labeled bag
Tip the tray back into the bag with the matching code. Label a replacement bag before transferring anything. Set an unidentified gem aside until you can match it confidently in daylight.
Cover the adhesive before moving the piece
Lower the original protective film in its original orientation over the unfinished area. Store a rigid acrylic design flat, with no heavy objects pressing on the gems. Keep the display stand with the pen and instructions.
Leave a starting point for next time
Photograph the corner you last worked on and slip a note with the next symbol beside the pen. Pack away the empty tray and closed bags together, out of reach of small children.
