After much deliberation I finally decided to go with Daisy Design Shop's Mason Jar Stationery on Etsy run by the lovely Samantha:
I went for the file only option which she offers at excellent value, which is a great idea as it then doesn't matter at all that we are on the other side of the world to each other. I just loved her designs and I knew she was for me.
Samantha, I really must say has been an absolute God send, so accommodating, fantastic with advice, always happy to communicate and discuss and amend designs and saw it as a process. She genuinely does care about your custom design being perfect for you - and I am so grateful to her for that - it really is a special level of service which she provides and I wouldn't hesitate in recommending her to all.
Next challenge was were to get it all printed. I did look at a local printers, but for the quantity I wanted it just wasn't good value for money unfortunately. So I decided to look at VistaPrint who I knew were a massive international online printers and I knew their printing would be good value for money, but I was genuinely pleasantly surprised by their quality of customer service and their print quality too. Again, I would recommend them highly. The one tip I have with using them, is to use their website to search out what you want but make sure you call them to order as you will get a much better deal, free items and they are up for bartering so do go for it!
I did give Samantha a pretty extensive brief to work with and she really did create exactly what I was dreaming of and so much more:
cute PDF creator before sending it to her. I included as much detail as possible along with images which I liked and colours.
Turner & Moss . The one down side of getting them printed myself is that I had to individually, with the Stanley knife pictured, cut slots in each backing card to secure the magnet in, this did take forever but was worth it in the end.
I changed to an American based wedding website in the end as I far preferred their templates called WeddingWindow; another lovely company with lovely and helpful customer service which again I would recommend.
