Hairspray fixes chalk so it doesn’t rub off.
Lots of toiletries come in baskets and they come in handy for paper etc
I use the take away boxes for all sorts but mainly for embossing powders as they are just right.
Charity shops often have small packs of buttons that are way cheaper than new
Tool rolls from b&q type stores store larger pens really well
When working parchment as in Pergamano, I always lean my hand on a piece of kitchen paper as I work so that any grease from my hand doesn’t spoil the parchment
When embossing parchment, if the tool doesn’t run smoothly, rub through your hair or on the side of your nose and it will run better!
I like my cards to smell nice so I have a body spray which I spray in the air and then wave my finished card through the mist. This avoids direct spraying which can leave water marks (as I found to my cost!)
I’m sure I have more but can’t think at the moment.
Hope they are of use to someone!
