I coloured some plain washi with alcohol inks, and put through the big shot - looks awesome, and you could use it straight away just like that! BUT
If you want to then colour with something like liquid pearls - they will dry and have a surrounding 'skin' that will ruin the project unless you cut it away or put it through your bigshot again!
A much better idea is to colour it first as below:
After it dries, put it through the big shot using your die:
And add to your project :-)
For the full reveal - stay tuned for tomorrow night :-D
Thanks for stopping by!
