Your cyanotype looks good, quite fancy giving them a go myself.
The hybrid process you describe is likely to result in the thread being closed however. Maybe try APUG's sister site DPUG instead?
(I also use enlarged digital positives for printing polymer photogravures, but don't discuss this on APUG as it's also a hybrid process and therefore outside APUG's scope).
These links might also be useful for materials:
Hope this helps
Edit: - just had a look at your APUG gallery - some great stuff in there...
