I have had a bit of a try with the hapazome. I did not prepare very well and the results are a bit hapharzard. However I did enjoy it and will do it again. I used the iron to heat set the fabric but wonder if I should use some textile medium as well. Anyway I will attach some pics.
I found that some of the harder leaves worked better than the soft ones and some flowers didn't work at all. However I will give it another go.
