Abstractly, on the topological circle $S^1$ there are only two real line bundles, up to isomorphism: the trivial one $\mathcal{O}$ and the Moebius strip $\mathcal{O}(1)$ (thinking of $S^1$ as $\mathbb{RP}^1$). So we have $\mathcal{O}(2k)\cong\mathcal{O}$ and $\mathcal{O}(2k+1)\cong\mathcal{O}(1)$ for any $k$.
Let's embed $S^1\hookrightarrow\mathbb{R}^3$ as the set $x^2+y^2=1$ in the $z=0$ plane. We can embed the total spaces $\iota_n:\mathrm{tot}(\mathcal{O}(n))\hookrightarrow\mathbb{R}^3$, respecting the zero section, for example as the union, for $t\in [0,2\pi]$, of the (open) segments joining the two points
$((1\pm\frac{1}{2}\cos(nt))\cos(t), (1\pm\frac{1}{2}\sin(nt))\cos(t), \pm\frac{1}{2}\sin(nt))\in\mathbb{R}^3$.
Call $\mu(n)\subset\mathbb{R}^3$ the so obtained $n$-twisted Moebius strips.
Is $\mu(2k)$ (ambient) isotopic to $\mu(0)$, and $\mu(2k+1)$ to $\mu(1)$?
(of course, properly, we're talking about the embeddings $\iota_n$)
