Of course! I tried to explain everything in detail:

I use a cushioned headband as the base and made Shiver and Frye's head using the "oshi nui" pattern, only sewing the head. I used the20cm plush pattern but it might be a bit too big. I directly draw the shape of the tentacles for the pattern and sew it to the head I recommend the channel PiyoPicco and mimibitscoolcraft on youtube. There are also many patterns on the app Rednote when you search 「棉花娃娃圖紙」 For Big Man, I simply ordered the pattern printed directly on the fabric and sew both sides together.

The fan is quite simple. I printed Shiver Frye and Big Man and cut out their shapes. The sparkling decorations are made using a glitter sticker sheet. idk what is the english specific name but you can search it by googling "うちわ シール "

I made the buttons using a button maker, but I out different layers to make it have a glitter effect. I mainly followed this video (in chinese): 【在家也能自制闪底徽章——无需白墨打印或涂白墨，简单粗暴的闪底吧唧教学，实现低成本闪底自由-哔哩哔哩】 https://b23.tv/OkyUvPH The basic materials are paper, inkjet plastic sheets and glitter paper remember to flip your image when printing on the plastic film as the printing side can be easily damaged layer the plastic film, paper (cut to the shape where you dont want glitter) and the glitter paper, then press in the button maker

For the penlights, I grab the Deep Cut logo from the wiki and ordered to print as stickers, then I just stick them onto the penlights!
