Hello!
When I went to last year's Kumoricon (which was my first ever anime convention! Such a delightfully silly time.) I heard about the plushie workshop (I don't care if I'm a grown 20-something man, I have a soft spot for stuffed toys!) and wanted to go.
However, I found out on the day of that there was a sign-up for the event and once it's filled it's filled, and that signups for both days occurred on opening day (ergo, I came in the second day thinking I'd be able to sign up and realized I was too late).
I just wanted to suggest that in the future it might help to make it clear that events like this have limited space and limited signup that's first-come-first-served.
Hope this is useful to know!
Sorry I did not bring this to anyone's attention sooner---purely my fault. I was lazy.
Looking forward to this year's events! The con is on my side of the river this year, and I've already placed my pre-order. Should be able to see much more of the con this year (last year I just sort of went in tourist mode).
