I have been watching the lessons for the Sew Retro Bombshell Dress on Craftsy.com. There are a few tools that Gretchen uses, that I think would come in handy. She gives US links, but I've tried to track some of these things down in UK/ Europe.
Bracelet Pin Cushion
I have found it impossible to find anyone selling this fancy pin cushion bracelet in the UK but you can get it in France (except the postage to the UK is ridiculous! I could almost swim to France from where I live !!! Crazy) It's by Bohin - called a bracelet (dore) pelote velours. Here are some links : shop 1 & shop 2. Can anyone explain why postage to the UK is sky high from France?
If anyone knows of a UK shop selling these, please share! I have to say I think I would feel very professional wearing this as I sewed!
This is not as glam as the pin cushion, but probably more useful! It's for ironing curved seams on. Costs around £10. Link 1 and Link 2.
This is the biggest layout for any keen dressmaker. But what a brilliant tool. Great selection from here. I would love one of these. Expect to pay £100 - £150.
Waxed Tracing Paper
Gertie gets it from here. Not sure where you get this from in the UK. Have you ever seen it for sale? Following a thread on a sewing forum, people like the Clover Chacopy tracing paper. Get it here for £3.31 + p+p. You will need a tracing wheel/ pen as well.
Do you have any must have dressmaking tools? Or any that are a waste of time?
