I'm thinking about making a cardigan and matching skirt. I am TERRIFIED that my ends will come undone. How can I make sure this doesn't happen? Is there a special glue I can use? If so, will it hold up if I wash the wearables? I can NOT wrap my head around the idea that I won't end up standing with a pile of yarn at my feet lol. Any advice would be super appreciated, thank you in advance!

Does anyone on here have any experience with crocheting a picture blanket? I was thinking of trying it out but have no idea where to start. I considered Tunisian but then I saw where someone else used single crochet. I the pictures I need in a pixel art form, but I don't know how to actually create what I am seeing in my head. I am including a picture of what my idea will basically look like. I tried reaching out to someone who did something similar but unfortunately it seems like they are no longer available on the platform I found them on. Thank you in advance to anyone that can help me out!
