Lacy rock

Never knitted lace before. I just had to try. So this is the result of two weeks knitting. A lot of ripping...
I am now done with the lacy knitting, the rest is in garter stitch. I wonder, though, if this will ever look like this?

However, the allconsuming question, as it is in lot of knitting - do I have enough yarn to finish it? Travelling across the sea and half of the US to get more does not sound like a solution. Crossing toes (as I can't cross fingers AND knit at the same time:))
