I popped into Lidl last night - it's a little out of my way, so it's not a frequent stop, but I was passing. I was so thrilled to see this selection of sewing threads - 28 bobbins and matching reels (plus a bit more) for £3.49! I bought three metal bobbins recently and the cheapest I found were 18 p each. So a true bargain. It's also lovely to have them pre loaded.
If you have a local Lidl and love sewing, it's worth popping in this week.
