#craft question

Generally I like using pen to mark out my pieces, but I’ve never actually washed any projects cause I’m a little worried it’ll just bleed and ruin the fabric, not washing out all the way. Is there anyone who’s had experience using pen, and does it wash out of fleece/plushies?

I was working on these quick and easy needlefelted keychains...but I finished two and I really don’t like how they’ve turned out at all...any needlefelters...help me...how do I get the finished product ultra smooth like I see on other craft photos?  Mine are always so fuzzy, no matter how many times I stab it (STABBUSTABBU) or trim it.  How do I fix this?

So last year I made Thomas a black board for this birthday with all his favorites and stuff. I plan on doing it again, last year I used metallic markers on a black poster board and worked great but I wanted more vibrant colors. When I did our pregnancy announcement I used chalk markers but they smug a lot, is there something you can put on over so that it doesn't smug?

Question: Will hot glue work on fabric because I don’t know if I have enough safety pins and I don’t have time to sew everything on?
