what are you using to get those nice sharp lines for your spin dyes? I tried a (cheap) paint brush, and a q-tip, and I can make a circle, but nowhere near anything as crisp as yours.
And your marbling is masterful (said Capt. Obvious).
The last two you posted, did you 'push' the disc down into the SC bath to get the swirls? They're just soooo awesome...
