Camp Nelson at Nelson’s Produce Farm
We had the best time bringing our squishy kits to mother-daughter movie night! Seeing so many familiar faces—kids who have celebrated on the trailer and parents who have cheered us on—made this night extra special.
Thank you, Nelson’s Produce Farm, for having us, and thank you to every family who stopped by. We’re so glad we got to be part of it and can’t wait to do it again! 💕
Our little pink corner was filled with custom slime, take-home kits, new friends and so much fun. Thank you to everyone who stopped by and made these weekends so special!
Besties were here 💕Guests picked their slime and made it their own with colorful toppings and mix-ins. And the fun didn’t stop at the booth—our DIY kits brought a little Besties magic home, too.
