I've not contacted Claire yet so what I'll do is just post some standard text here and then anyone can copy and paste it and edit it to fit....
Thanks for your interest in the link swap at Crafteroo. We would need you to supply us with a portrait format A6 graphic to advertise your website or blog for inclusion in our next issue of the magazine. We need to receive this by 16th June if at all possible due to publication deadlines. Please send to email@example.com
as a jpg, gif or PDF, making sure it's at least 100kb. If files are compressed too much they will look pixelated which isn't good for either of us!
We will send a button over to you in reply to receiving your advert. It is currently 250px square, so please let us know if it won't fit in your template and what (square) size would suit you better if it isn't appropriate. Please set the graphic to go live on your blog or website no later than 1st July so it corresponds with your advert. We will display your advert for 3 months so we would appreciate it if you could do the same for us!
