I learned recently how expensive framing is. I was looking to get a much smaller picture framed 50cm x 40cm and cheapest quote I got was €150. That was in 3 different frame places.
Only one I didn’t make it to actually was AM Frames in Drumcondra which was just recommended to you.
I ended up getting an IKEA frame for €16 and to be honest it in bang on. Not as sturdy but it will do the job.
