Re – the question about framing.
Never take your work to someone who is not familiar with needlework. They often use mounting boards which have glue on them. The glue will leach through in no time and your work will be ruined. You can never get it off again.
Having said that, if you don’t trust your framer, do it yourself. Mount your piece on acid-free foam core with pins or lacing and then take it to a framer.
This method is cheaper because you have done most of the work. Also choose your frame carefully. I always try have it suit the period of the sampler.
I do a lot of 17th century pieces so I don’t want anything that is modern or colonial in appearance.
I like the idea of hem stitching but if the piece is very long or heavy it can sag over time.
When mounting this type of finish you should try to take a number of invisible stitches throughout the piece to hold it in place.
I don’t use glass because I like to be able to see the work without it but if I do I use regular glass or the expensive ultra violet or whatever it is. The non-glare glass makes the work appear flat and takes away the beauty of your stitches.
Hope this helps.
