Let customers speak for us
Such a wonderful box filled with unique items! I love the metal boxes!
Thanks for the help making my home pretty!
I have to admit: I began to wonder how many more things from the MM boxes I could fit in my house. I wondered if the latest might be my last. Welp ... nope! I loved this box and can't wait for the next. Thank you, MM, for making my house look a bit more stylish every quarter and delivery day feel like my personal Christmas -- I LOVE it and can't wait for the next!
I really don’t know how Morgan does it, every time (and I’ve been receiving boxes since the first shipment), as I unwrap its like she reads my mind what I would love to add to my home decor. She is the best.
Thoughtfully crafted with pieces that will age well for many seasons to come.
I love receiving the Live Simply Box. It is filled with wonderful items and is very fun to open.
I loved every item in this box this time! Keep'em coming!!
I look forward to this box every season. Morgan continues to raise the bar with amazing finds making it such a great value.
… it’s an event. My mom, sister and I are giddy when we see the unopened box sitting there waiting to be opened. And as we settle in and ensure undivided attention as we unveil each item inside, our smiles are big and the ooooh’s and ahhh’s continue. Seriously! Makes us so happy and can’t wait to find the perfect spot. I always say I’m going to share but it’s a big ole lie! I keep it all. We also love the description booklet that comes with each box and the recipes, too. Here’s a pic from the Fall’24 box showing some ways I have used the items. Thanks, Morgan!
I have been on a high since completing Morgans amazing work shop! If you are ready to take your business to the next level, don’t think twice and get yourself registered. I’ve already been able to put to use the wealth of knowledge she provided that my business will benefit greatly from. So so thankful for this work shop and love the relationships that were formed.
Just received my Fall ‘24 box and it was amazing. So many unique items that will make my home decor one of a kind. Opening each item is so fun. Can’t wait for the next one.
Morgan’s workshop has been a game-changer for my business. Her coaching provided a perfect mix of creative insight and practical business advice, helping me refine my design process and elevate my brand. Beyond her expertise, Morgan is incredibly supportive and genuinely invested in helping others grow. She took the time to understand the unique challenges and goals of each person in the group and offered personalized guidance. I highly recommend the Design Your Life Workshop to any interior designer looking to enhance their skills, grow their business, and thrive in this industry.
This class is invaluable to anyone looking to start or level up their design business. I’ve been extremely nervous about starting a design business and had no clue about pricing, sourcing, contracts, LLCs, etc. Morgan took her time to answer all our questions and gave each one of us the attention we needed as it pertained to where we were at. The separate chat group has been so helpful and created such a great sense of building each other up. Thank you Morgan for giving me such a great sense of direction on how to start my business!
