Few "issues" along the way (aka mistakes): 
* two of the corners shifted a bit so I had to use the screw driver trick to close the edges (thankfully the top looks ok)
* a few of my walnut splines weren't sanded down enough so I couldn't get them fully in the slots AND then they wedged so I couldn't remove BUT my husband was nearby so he was able to remove the half-seated splines so I could find ones that fit - that happened three times 🙄

So, there have been some situations but handled and moving forward.  I doubt I'll ever have a "perfect" project, but always try my best!
