Yay, I just made my first sale! I listed my first poster three weeks ago. Celebrating the little wins :-)

Hello everyone, I’m brand new here and have just published my first listings in the nursery niche. I would really appreciate your feedback on the designs and the listings. https://www.etsy.com/shop/WindowlightStudio I also have a question: I set the quantity to 99 for all listings, but buyers still can’t select a quantity when ordering (see screenshot below). Has anyone experienced this issue? Unfortunately, Etsy Support hasn’t been able to help me. Thank you!

Hi everyone, I’m currently working on my first designs. I created them in Midjourney and upscaled them using Upscayl. The final dimensions are 5472 × 7776 px. Would that resolution be enough for printing in A0 format? My plan is to design in one A format and then adjust the size once I receive an order. Thanks in advance for your advice!
