Daydreaming about these gorgeous Sophia Webster resort sandals
DIY Metal Tape Embossed Box Tutorial from EPBOT. All you need is a surface to cover, aluminum foil tape (metal tape) from the hardware store, paint and bits and pieces to cover. I included the lower right hand photo - Jen’s friend Renee’s notebook cover - because I just got a message asking about ways to cover notebooks.
DIY Steampunk iPhone Gramophone Novelty Speaker Tutorial from Cici Bean here. This DIY cost around $10 to make and you need a drill for this. She also used a funnel for the horn to keep the price down. The ultimate verdict on the sound was not great but you could move the “horn” around to project the sound in different directions.
Not a DIY but a remarkable bag by Etsy Store Jungle Tribe for $269 here. Steampunk or cosplay gear and inspiration. The attention to detail is amazing. Also check out their Jungle Tribe Couture site here and look at the detailing on the savage skirt.
